Abstract (en)
1. Movement-compensating device (10), at or in machines for the processing of synthetic material fim webs for the production of bags, sacks or the like, which is arranged between a continuously operating feed equipment (13, 14 ; 36, 37) or an intermittently operating feed equipment, and consists of a first group of deflecting rollers (22), which are arranged in one plane and borne to be locally fixed at the machine frame, and of a second group of deflecting rollers (29), which are arranged in one plane and at a rocker arm (27, 44) pivoting to and fro about an horizontal rotational axis (25, 45) and in co-operation with the locally fixed deflecting rollers guide the film web in loops, characterized thereby, that the rocker arm (27, 44) is arranged with its deflecting rollers (29) in its initial setting for the drawing-in of the film web between both the groups of deflecting rollers (22, 29) at a small spacing parallelly or nearly parallelly from the plane of the locally fixed deflecting rollers (22) and the rocker arm (27, 44) is pivotable into its operative setting after drawing-in of the film web (15) through the space between the plane of the locally fixed deflecting rollers (22) and the plane of the deflecting rollers (29) arranged at the rocker arm (27, 44) in the manner that the deflecting rollers (29) arranged at the rocker arm are movable through the plane of the locally fixed deflecting rollers (22) and through between these and thereafter in co-operation with the locally fixed deflecting rolllers (22) lay the film web (15) into loops.
