发明名称 A METHOD OF AND AN APPARATUS FOR TRANSFERRING A FAST RUNNING READY-DRIED FIBROUS WEB, ESPECIALLY A TISSUE WEB, FROM ONE DEVICE AND ALONG A PREDETERMINED RUN TO A SUBSEQUENT DEVICE
摘要 To accomplish a web transfer, which in reliability is comparable to the one obtained with a closed draw, in any operating environment, but especially where it is desirable to transfer a fast running tissue web (4) from the drying section of a tissue machine, e.g., a yankee dryer (2), to a reel-up (3), a web support device (10) extends across the width of the web (4) and along a predetermined run of the web (4) from the yankee dryer (2) to the re el- up (3). The web support device has a support surface (11) formed by a series of plate member assemblies (23) having means for creating a flow of air in t he direction of the web run. Between the web (4) and the support surface (11) t he flow of air forms an air layer (15) of reduced static pressure, so as to stabilize the web (4) against flutter. The predetermined run may extend through a calender (7) and past scanner equipment (8). Pneumatic tail threading capabilities may be included.
