Abstract
The invention relates to a pin-setting apparatus for bowling or skittle lanes (3′-6′) comprising a plurality of pins (3-6), wherein each pin is connected to an associated string (3′-6′). The apparatus comprises for each pin (3-6) a rotatable pulley (13-16) arranged to roll up and/or off the associated string (3′-6′) and detecting means arranged to detect a movement of the pin (3-6) when hit directly or indirectly by a bowling ball, and activating means arranged to rotate the pulley (13-16) so as to roll off the string (3′-6′) as soon as the pin (3-6) gets hit. This way, the pin (3-6) will not be obstructed by possible tension in the string (3′-6′) and will move as if it was not attached at all.

A pin-setting apparatus for bowling or skittle lanes, the apparatus comprising:
- a plurality of pins, wherein each pin is connected to an associated string;
- a plurality of rotatable pulleys, each of the plurality of rotatable pulleys being arranged to roll up and/or off an associated string of a corresponding one of the plurality of pins;
- a plurality of detecting means, each of the plurality of detecting means being arranged to detect a movement of a corresponding one of the plurality of pins;
- a plurality of electrical motors, each of the plurality of electrical motors being arranged to rotate a corresponding one of the plurality of pulleys, and
- a controller arranged to receive from each of the plurality of detecting means input relating to movement of a corresponding one of the plurality of pins and to control each of the plurality of electrical motors arranged to rotate a corresponding one of the plurality of pulleys in such a way that the corresponding pulley's associated string is actively rolled off as soon as the movement of the corresponding pin has been detected.
