Needs Different Contact<\/h2>\n<p>The first haul-off pulls the sheet from the calibration section, often before the profile has gained full stiffness.<\/p>\n<p>Consider two hollow sheets of the same overall thickness. One has closely spaced ribs and relatively thick skins. The other has wider cavities and thinner walls. Under similar roller pressure, the second profile may be more prone to local indentation, particularly while it is warm.<\/p>\n<p>This makes the actual cross-section useful when selecting a replacement cover. The outer thickness alone cannot show how the internal structure supports the roller load.<\/p>\n<p>Some PP hollow-sheet machines use several rubber-covered rollers in the first haul-off. With suitable contact and coordinated drives, multiple roll pairs can share the pulling duty and reduce the load concentrated at one contact. This arrangement is particularly relevant while the profile is still relatively soft.<\/p>\n<p>A later haul-off may receive sheet that has undergone further processing and cooling. Its cover should therefore be matched to the condition at that position rather than automatically copying the first puller\u2019s specification.<\/p>\n<p>For the broader application requirements, see <a href=\"https:\/\/wolorin.com\/de\/applications\/plastic-sheet-and-board-processing-rollers\/\">Walzen f\u00fcr die Verarbeitung von Kunststoffplatten und -tafeln<\/a>.<\/p>\n<h3>Which Haul-Off Position Are You Replacing?<\/h3>\n<p><strong>First haul-off \u2014 The sheet may still be warm and relatively soft.<\/strong><\/p>\n<p>Check the hollow cross-section and whether the original contact has caused cavity collapse. The cover must provide enough grip without damaging the internal structure.<\/p>\n<p><strong>Later haul-off \u2014 Further processing and cooling may have increased sheet stiffness.<\/strong><\/p>\n<p>Identify the original cover specification and confirm the sheet condition at this position. The equipment team should verify contact and speed coordination with the upstream puller.<\/p>\n<p><strong>After full cooling \u2014 The profile has reached its cooled state.<\/strong><\/p>\n<p>If another rubber-covered pulling or handling roller is installed here, identify its actual duty and original construction before ordering a replacement.<\/p>\n<p>The number of roll pairs and their arrangement vary by machine. Confirm the installed assembly before ordering replacement rollers.<\/p>\n<\/div><div class=\"wl-wrap wl-section\"><h2>When More Grip Starts Crushing the Cavities<\/h2>\n<p>If increasing nip pressure reduces slipping but leaves flattened cavities, compare the sheet immediately before and after the suspected roll pair.<\/p>\n<p>Look at the hollow cross-section. A shallow impression on the outer skin is different from a cavity that has lost height. The second condition shows that the internal profile has been compressed.<\/p>\n<p>The location of the damage helps narrow the cause.<\/p>\n<p>For example, if the sheet enters one roll pair with intact cavities and leaves with several flattened channels near one side, check the corresponding area of the roller face.<\/p>\n<p>A worn band on the cover at the same width position strengthens the reason to inspect that pair. If existing operating records also show that increasing pressure makes the same cavities flatter, roller contact becomes a more credible contributor.<\/p>\n<p>The next step is to examine how the cover makes contact.<\/p>\n<p>A worn or polished surface may have lost some of its original grip. Increasing pressure to compensate can place more load on the hollow structure. Uneven contact across the roller face can concentrate that load in one part of the sheet.<\/p>\n<p>When specifying a replacement, examine the cover\u2019s surface condition, hardness, thickness, and compression behavior together. The required grip must be achieved within the compression the sheet can tolerate.<\/p>\n<p>A softer cover may change the contact area and deformation under load, but softness alone cannot establish whether the hollow ribs will be protected. Surface grip and the actual mating contact matter as well.<\/p>\n<p>For positions where the rubber-covered roller forms a controlled nip, see <a href=\"https:\/\/wolorin.com\/de\/function\/pressure-rollers\/\">Andruckwalzen<\/a>.<\/p>\n<p>The damage pattern can also point away from the roller.<\/p>\n<p>If the cavities are already distorted before entering the haul-off, the forming or cooling process needs attention. If a new sheet specification develops widespread collapse without a corresponding local roller-wear pattern, its wall thickness and cooling condition should be checked before changing the cover.<\/p>\n<\/div><\/div><style>\n.wlr-post,.wlr-post *{box-sizing:border-box}.wlr-post{max-width:1120px;margin:0 auto 24px;color:#263b50;font-family:inherit}.wlr-post .wl-wrap{background:#fff;border:1px solid #e3eaf0;border-radius:20px;padding:42px 46px;margin:0 0 24px;box-shadow:0 12px 32px rgba(17,52,82,.055)}.wlr-post .wl-wrap:nth-child(even){background:#f6f9fc}.wlr-post h1,.wlr-post h2,.wlr-post h3{color:#173a58;line-height:1.22;letter-spacing:-.02em}.wlr-post h1{font-size:clamp(30px,3.1vw,43px);margin:0 0 26px}.wlr-post h2{font-size:clamp(26px,2.5vw,33px);margin:0 0 25px;padding-left:16px;border-left:5px solid #e1a318}.wlr-post h3{font-size:21px;margin:31px 0 17px}.wlr-post p,.wlr-post li{font-size:16px;line-height:1.72}.wlr-post p{margin:0 0 26px}.wlr-post p:last-child{margin-bottom:0}.wlr-post ul,.wlr-post ol{margin:0 0 26px;padding-left:24px}.wlr-post a{color:#126a9b;text-decoration:none!important;border:0!important;box-shadow:none!important;transition:color .22s ease,background-color .22s ease,transform .22s ease}.wlr-post a:hover,.wlr-post a:focus-visible{color:#c18a11;text-decoration:none!important}.wlr-post a:focus-visible{outline:2px solid #e0aa2b;outline-offset:3px}.wlr-post .wl-hero{display:grid;grid-template-columns:1.12fr .88fr;align-items:center;gap:40px;background:#f4f8fb}.wlr-post .wl-hero-media img{display:block;width:100%;height:auto;max-height:420px;object-fit:contain;border-radius:15px;background:#fff}.wlr-post .wl-table{overflow-x:auto;margin:14px 0 29px;border-radius:13px}.wlr-post table{border-collapse:collapse;width:100%;min-width:610px;border:0!important}.wlr-post th,.wlr-post td{padding:14px 16px;text-align:left;vertical-align:top;border:0!important;border-bottom:1px solid #e4eaf0!important;font-size:15px;line-height:1.6}.wlr-post th{background:#eaf1f7;color:#173a58;font-weight:700}.wlr-post tr:nth-child(even) td{background:#f7f9fb}.wlr-post .wl-related p:has(>a){margin:20px 0 12px}.wlr-post .wl-related p>a{display:inline-block;background:#eaf2f9;border-radius:10px;padding:11px 17px;font-weight:700;color:#146d9d;transform:translateY(0)}.wlr-post .wl-related p>a:hover,.wlr-post .wl-related p>a:focus-visible{background:#fff1d2;color:#9b6800;transform:translateY(-2px)}.wlr-post .wl-cta{background:#173b5b!important;color:#fff;border-color:#173b5b;padding:42px 46px}.wlr-post .wl-cta p{color:#f2f7fb}.wlr-post .wl-cta-actions{display:flex;flex-wrap:wrap;gap:14px;margin-top:28px}.wlr-post .wl-cta-actions a{display:inline-flex;align-items:center;justify-content:center;min-height:47px;padding:12px 20px;border-radius:9px;font-size:15px;font-weight:700;transform:translateY(0)}.wlr-post .wl-cta-actions a:first-child{background:#efb52e;color:#173b5b}.wlr-post .wl-cta-actions a:last-child{background:#fff;color:#173b5b}.wlr-post .wl-cta-actions a:hover{background:#f8d779;color:#173b5b;transform:translateY(-2px)}@media(max-width:767px){.wlr-post{margin-bottom:18px}.wlr-post .wl-wrap{padding:25px 20px;border-radius:15px;margin-bottom:18px}.wlr-post .wl-hero{grid-template-columns:1fr;gap:21px}.wlr-post h1{font-size:30px}.wlr-post h2{font-size:25px}.wlr-post h3{font-size:20px}.wlr-post p{margin-bottom:22px}.wlr-post .wl-cta-actions{display:grid;grid-template-columns:1fr}.wlr-post .wl-cta-actions a{width:100%}.wlr-post table{min-width:560px}}\n<\/style>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d945fef elementor-widget elementor-widget-html\" data-id=\"d945fef\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"wlr-post wlr-post-part-3\"><div class=\"wl-wrap wl-section\"><h2>What the Old Roll Pairs Reveal<\/h2>\n<p>On a multi-pair haul-off, compare the rollers instead of assuming they have worn at the same rate.<\/p>\n<p>One damaged cover among otherwise healthy rollers may point to an isolated replacement. The upper and lower rollers should be checked separately, since the mating roller or uneven loading may also be involved.<\/p>\n<p>Several pairs showing unusual wear suggest a wider contact or operating problem. If the sheet is being dragged between driven pairs, the equipment team should verify their surface speeds and contact conditions.<\/p>\n<p>A new rubber cover cannot correct an incorrect drive relationship. That problem needs machine-side attention before the roller specification is changed.<\/p>\n<p>For a confirmed rubber-covered pulling position, the broader functional requirements are covered under <a href=\"https:\/\/wolorin.com\/de\/function\/traction-rollers\/\">Zugwalzen<\/a>.<\/p>\n<\/div><div class=\"wl-wrap wl-section\"><h2>When to Keep the Original Cover Specification<\/h2>\n<p>If the original roller has performed well and only the cover has worn through normal service, a like-for-like replacement is usually the simplest route.<\/p>\n<p>Start with the original drawing or confirmed specification. Identify the rubber-covered component in the roll pair and confirm its finished outside diameter, face length, cover thickness, core construction, and shaft-end details.<\/p>\n<p>A heavily worn roller may have lost diameter. Its current measurement should be checked against the original specification before manufacturing a replacement.<\/p>\n<p>The cover deserves a fresh review when the working conditions have changed or the old problem keeps returning.<\/p>\n<p>For example, a customer may switch to a hollow sheet with thinner skins or wider cavities. The original roller dimensions may still fit the machine, but the cover must now work with a profile that may tolerate less compression.<\/p>\n<p>A change in cooling conditions can have a similar effect at the first haul-off. If the existing cover can maintain grip only at a pressure that damages the sheet, copying its original hardness and surface finish may reproduce the problem.<\/p>\n<p>Keep the confirmed mounting dimensions. Review the rubber compound direction, cover thickness, hardness, and surface finish against the new contact requirement.<\/p>\n<p>For routine replacement, Wolorin can proceed with custom manufacturing, quotation, or production confirmation from drawings, samples, or clear specifications. For changed applications, the sheet cross-section, actual roller position, and old cover condition help establish what needs to be revised.<\/p>\n<\/div><\/div><style>\n.wlr-post,.wlr-post
