Abstract

A bowling center system includes: a bowling lane; a plurality of pins positionable at predetermined points on the bowling lane; a plurality of strings, associated at one end, with a corresponding pin (2); for each string, a constrain system positioned above the bowling lane and having the other end of each string connected to it; a pulley system for managing the strings, positioned between the connecting system and the pins and including a motor-driven drawbar operatively configured to manage a predetermined length of each string present along the pulley system; the drawbar is movable between a first position, allowing the pins to be lifted from the bowling lane, and a second position, allowing not only the pins to be lowered onto the bowling lane into the predetermined position but also each string to be slackened by the release of a further first working length so that the pins can fall freely when struck by a ball thrown along the lane or by other pins struck by the ball during play; a control device for controlling the position of the movable drawbar; and a drive and selection system connected to the movable drawbar and to the control device and configured to allow the movable drawbar to move, when required, to at least a further, third operating position allowing the string to be slackened by the release of a second working length different from the first working length of string released when the second operating position is reached.
