Abstract
Abstract By means of winder gearing maintaining essentially constant the winding speed a drive motor drives a winding mandril. Operatively associated with the winding mandril is a winding band which is paid-off of a freely rotatable supply roll. Engaging at this supply roll is a jaw brake. The winding or wind-up band is guided over a balance or rocker arm which is upwardly and downwardly pivotable about a pivot axis. By means of a contact or pressing mechanism the balance arm is pressed against the winding mandril. The imbricated printed product stream, infed from a band conveyor, arrives at the balance arm or rocker and the winder band and is supported thereat. The thus supported imbricated printed products are infed from below to a winder gap and in conjunction with the winder band wound-up on the winder mandril. The winder band separates the individual wound layers or plies from one another. By braking the supply the winding of the winder band is accomplished with tension, so that there is formed a snug or tightly wound package in which the printed products are unable to alter their position within the imbricated product formation or stream. Due to the bottom or underfeed of the winder band and the printed products reposing thereon there is required only a single winder or winding band. To ensure for an adhesion between the surface of the winder band confronting the imbricated product formation and the printed products the winder band preferably is formed of an adhesive material. As a further possibility this winder band surface can be rendered adhesive in a suitable manner or provided with an adhesive coating.
