Abstract:
1. A unit for feeding labels in a packer machine for tobacco products, comprising a channel presenting an infeed end and an outfeed end, in which to accommodate a stack of labels, a take-up station, associated operationally with the outfeed end of the channel, from which the labels are taken up singly and transferred to a user machine, and a mechanism by which to transfer a succession of labels, operating between the outfeed end of the channel and the take-up station, wherein the take-up station is capable of movement relative to the outfeed end of the channel in response to a pressure exerted on the take-up station through the succession of labels transferred by the transfer mechanism, and the transfer mechanism is interlocked to a feedback control in such a way that the pressure exerted by the succession of labels on the take-up station can be maintained within prescribed values, wherein the take-up station comprises at least two abutment members operating on opposite sides of a label at the take-up position and slidable along axes parallel to the longitudinal axis of the stack of labels in response to the pressure exerted by the labels on the transfer mechanism.
