Abstract

A holding and supporting group of a winding spindle in a machine for winding plastic film onto spools includes a winding reel positioned between two uprights, wherein a first upright carries a rotating plate which cantilever-supports three spindles and a central shaft, wherein the central shaft is supported at the other end by the second upright, wherein, in correspondence with a free end of the central shaft, there is a star-shaped plate with three supporting arms for each free end of the three spindles through a respective toggle lever mechanism driven by an actuator carried on a lever articulated with respect to the star-shaped plate, and in turn caused to oscillate between an operative blocking position of the respective spindle and a rest position for releasing the respective spindle by an additional actuator.

Dependent claims

A holding and supporting group of a winding spindle in a machine for winding plastic film onto spools, comprising:

a winding reel positioned between a first and a second upright (12,13),
wherein the first upright (12) carries a rotating plate (14) which cantilever-supports three spindles (16,17,18) and a central shaft (15),
wherein said central shaft (15) is supported at an opposite end by the second upright (13), and
wherein, at one end of said central shaft (15), there is a star-shaped plate (19) with three supporting arms for each free end of the three spindles (16,17,18) through a respective toggle lever mechanism (21,22,25) driven by an actuator (30) carried on a lever (20) articulated with said star-shaped plate (19), said lever being caused to oscillate between an operative blocking position of the respective spindle (16,17 or 18) and a rest position for releasing the respective spindle (16,17,18) by a second actuator (32).
