Storage device for binding wire of a cording machine

摘要

An accumulator device (1) for the tying wire of a tying machine used in pulp production has a drive (3) at the inlet to the accumulator device and another drive (7) at the outlet from the accumulator device. By means of the accumulator device (1) according to the invention and the two drives (3, 7), it is possible to store the entire length of wire required for one tying cycle temporarily and then to remove the wire from the accumulator for the tying cycle. In this way, a dynamic accumulator volume is created for the tying wire in the accumulator device (1).

1. Accumulator device for tying wire in a tying machine, comprising:
a vertically elongated frame having an inlet side and an outlet side, an upper roll supported by the frame a distance above a lower roll supported by the frame, a roll guide extending vertically and fixed with respect to the frame, for guiding vertical movement of the upper roll within the frame whereby said distance between the upper and lower rolls is adjustable, a first drive mounted at the inlet side for receiving tying wire from a supply and urging the tying wire toward said rolls and a second drive mounted at the outlet side for receiving tying wire from said rolls and urging the tying wire away from the frame, wherein the tying wire passes from said first drive toward the frame where the wire engages the upper and lower rolls and loops at least twice around the upper roll and loops at least twice around the lower roll before passing to the second drive.
