Operation of the gathering and Wire-stitching machine

Model PEW DH2 Signatures and cover sheets are dropped on a circulating gathering chain and conveyed to the stitching station through the spine from the outside to the inside with the wire staples. The two stitching heads for stitching with two staples are arranged under a hinged guard. These can be easily set to the thickness of the material to be stitched and to changes of the distance between the staples. Two exchangeable stapling devices are supplied, one of them for thin and the other one for thicker wire-gauge. After the stitching operation, which can be performed with staggered or unstaggered position of the staples, the brochures are delivered in imbricated form on a belt delivery. Higher efficiency Auto-feeders Full utilization of the capacity of the gathering and wire-stitching machine DH2 can be achieved by connecting it with feeders operating according to the roll-off principle. The gathering and wire-stitching Model DH2 can be provided upto 4 Auto-feeders. If the machine is to be used for hand feeding, the feeders have simply to be swivelled back. These feeders are also suitable for polygraph flow lines and can be attached without any modification.
