ABSTRACT:
A stapling arrangement of a stapling and gathering machine includes a stapling carriage which is seated on a machine frame and travels with a gathering chain for stapling printed products carried by the gathering chain. At least one stapling head travels with the stapling carriage and with a bending device. A drive mechanism is provided for the stroke of the stapling carriage and the strokes of a shaping element and a punch of the stapling head. The drive mechanism includes a first drive for the stroke of the stapling carriage, and a second drive for the strokes of the shaping element and the punch, and for a movement of the bending device. The first drive can be exchanged independently of the second drive for adaptation to the pitch of the gathering chain. The stapling arrangement can also be converted quickly and easily to a different chain pitch by a semi-skilled operator. The bending device is supported such that it can yield downward when the products to be stapled vary in thickness, or when an overload occurs due to a paper jam. The bending device is preferably supported by springs.
