<p>A calender employs an open-stack like arrangement with a single vertical beam (32) or support column on each end of the calender. In combination with the support beam (32), a special swing link (34) is used to support tension loads on the open side of the calender. The nip is thus straddled by structural members between the support column and the link. This combination has the ability to support high linear nip loads, as high as 2,500 PLI or higher. The link has pin connections (38, 44) at both ends so that when one pin is removed, the link can be swung open for roll removal or accessibility. Thus, the strength of the closed-stack calender is combined with the visibility and ease of access of the open-stack calender by the employment of tension links which replace one of the support columns utilized in a closed-stack calender.</p> |
