Abstract
A binding line having selectable pin spacing on a gathering chain includes a gathering section including the gathering chain having a plurality of spaced pusher pins for transporting gathered signatures seriatim therealong to a signature exit end. A stitcher section includes a stitcher chain having a plurality of spaced pusher pins for transporting signatures seriatim therealong from a signature entry end. A drive system provides for driving the gathering chain synchronously with the stitcher chain so that both the gathering section and stitcher section operate at a constant signature feed rate. The gathering chain pins are spaced apart a first select distance and the stitcher chain pins are spaced apart a second select distance, different from the first select distance. The drive system drives the gathering chain at a different velocity from the stitcher chain to provide the constant signature feed rate. A transfer section includes a fixed saddle plate extending between the gathering section exit end and the stitcher section entry end and an endless overhead chain having a plurality of spaced pusher pins. A belt drive system includes a timing belt extending between a drive pulley …
