摘要

A bowling pin placing installation is used where the pins are suspended on draw-up reopes with an automatic winding drum. There is a swivelling see-saw coordinated with each rope and carrying rope reversing rollers. The pins placing installation includes drive and braking devices (7, 8, 9, 10, 13, 14, 15) by which a pull tension can be exerted in both directions of movement on to the rope section between the see-saw reversing roller (14) and the wind up drum (53). The wind up drum is axially adjustable by a spindle to form spiral shaped rope layers.
