Abstract:

An improved slow down system in sheet handling equipment which makes possible high speed handling of paper and plastic materials, including limp-bodied paper and plastic stocks, such as lightweight and recycled paper and plastic bags. In the prior high speed sheet handling systems, the slow down sections tend to jam because the limp-bodied sheets are easily deformed at higher speeds. A conventional snubber and a laydown device just following the high speed section of the sheet handling equipment lays down the trailing portion and edges of the first and successive incoming sheets, so that the lead edge of each successive sheet will clear all parts of the previous sheet. The sheets are squared by a tape slow down section, which comprises sets of adjustable slow down tapes with idler rollers and lower slow speed tapes with idler rollers, all running at the same speed. The idler rollers are adjustable so that the optimum stream can be obtained for any limp-bodied or lightweight sheets.
