Abstract

For the introduction of a strip of material between the rollers of a loop take-up apparatus having a fixed frame that includes one or more rows of rollers and a movable jockey frame that includes one or more rows of rollers, the rows of rollers are brought into a pull-through position and the strip of material is attached to a strip pull-through device and passed through between the rows of rollers situated in the pull-through position by means of the strip pull-through device. The pull-through device comprises a chain system which preferably consists of two finite chains which in the pull-through position can be guided in grooves at both sides of the rollers. The grooves are formed by guide grooves provided in the fixed frame and the jockey frame, which guide grooves are in line with each other and together form a continuous groove when the jockey frame is in the pull-through position.
