Abstract

(57) This publication describes a continuously running unwinder, for instance, for feeding a paper web from a reel-up drum into a supercalender. The unwinder proper comprises an unwinder unit (1), adapted on a base (11), an unwinder block (3) incorporated in the unwinder unit (1) for synchronizing a fresh reel-up drum (8) with a paper web (12), and a splicing head assembly (9) for splicing a paper web (12) from an expiring reel-up drum (2) by means of an doublesided adhesive tape strip on the surface of a fresh roll on the reel-up drum (8). In accordance with the invention, the expiring reel-up drum (2) can be elevated by lift actuators (4, 6, 7; 10), mounted on the frame of the supercalender (5) at least essentially vertically, from the unwinder block (3) to the unwinder block (3) of the fresh reel-up drum (8) to facilitate reel-up drum transfer and flying splicing. In accordance with a preferable embodiment, the lift actuators consist of carriages (4), mounted on the frame of the supercalender (5) and driven by drive actuators (7), gliding along at the essentially vertical mounted guides (6). The unwinder in accordance with the invention consumes less space, especially in the lateral direction, than inventions of prior art. (Figure 1)
