Abstract
A transport or conveying device is used in a folding apparatus for transporting or conveying signatures. A transport or conveying cylinder, which carries the signatures, is placed in cooperative engagement with another cylinder. A position of a terminal end of a signature carried on the transport or conveying cylinder can be altered. The other cylinder that cooperates with the transport or conveying cylinder includes devices that press on the signature and that displace the end of the signature.
Claims9
A conveying device in a folding apparatus comprising:
- a conveying cylinder adapted to convey signatures having leading and trailing signature ends;
- at least one further cylinder cooperating with said conveying cylinder and defining a cylinder gap, said further cylinder having a circumferential surface;
- at least one signature trailing end displacement strip extending axially on said further cylinder and projecting radially past said circumferential surface of said further cylinder;
- a signature trailing end displacement strip receiving groove on said conveying cylinder and located opposite said signature trailing end displacement strip as said strip passes through said cylinder gap, said signature trailing end displacement strip receiving groove being adapted to receive said signature trailing end strip, said signature trailing end displacement strip contacting said trailing ends of signatures passing through said cylinder gap and displacing said trailing ends of signatures conveyed on said conveying cylinder into said signature trailing end displacement strip receiving gap and in a circumferential direction of said conveying cylinder to form a signature spacing gap;
- and
- a signature leading end holding device on said conveying cylinder and adapted for movement in a radial direction of said conveying cylinder into engagement with said leading ends of signatures conveyed on said conveying cylinder.
