Abstract

An expandable shaft for wrapping a film comprising a substantially cylindrical central body (3), a plurality of first shaped leaves (5) and a plurality of second shaped leaves (6). Such leaves being alternated with each other and associated with the central body (3) by a plurality of pushers (8) which realise the radial movement thereof with respect to the central body (3). The latter comprising an actuator (22) to cause the pushers (8) to move and alternately arrange the leaves (5, 6) according to an operative configuration, in which the cross section (23) of the shaft (1) is continuously circular, and according to a resting configuration in which in the cross section (23) there are indentations (24) at the second leaves (6), and the diameter of the cross section (23) in the operative configuration is greater than the diameter of the cross section (23) in the resting configuration.

Abstract

The invention is a support (1) for the end pin (A1) of a shaft (A), comprising: a tube (2) suited to be associated with a supporting structure (S); a primary shaft (3) coaxially coupled inside the tube (2) and suited to be associated with power means suited to set it rotating; a prismatic seat (5) created in the end (4) of the primary shaft (3) and configured in such a way as to accommodate the end pin (A1) of the shaft (A); a sliding flange (6) associated with a shaped cap (7); moving means (8) suited to move the flange (6) between a first position (B) spaced from the tube (2) with the shaped cap (7) superimposed to the prismatic seat (5) and a second position (C) against the tube (2). Locking means (10) are provided to constrain the flange (6) to the projecting end (4) of the primary shaft (3) in the first position (B), as well as two manoeuvring rods (20, 21), each one of which cooperates with the locking means (10) when it is activated by an operator.

Abstract

The invention is a machine (3) suited to process the sliding surface (2) of a ski (1), comprising: a grinding wheel (4) that defines a longitudinal axis (X); first power means suited to set the grinding wheel (4) rotating around the longitudinal axis (X); a guide unit (7) suited to move the ski (1) according to an advance direction (Y) maintaining the sliding surface (2) in contact with the grinding wheel (4); a tool (8) suited to be positioned in contact with the grinding wheel (4) so as to impress a groove on the cylindrical surface (5) of the grinding wheel (4) that is set rotating; second power means suited to move the tool (8) according to a direction of movement (Z) parallel to the longitudinal axis (X); a logic control unit configured so as to operate the first and the second power means in such a way as to move the tool (8) according to the direction of movement (Z) depending on the rotation angle of the grinding wheel (4). The second power means are configured so as to vary the processing depth of the tool (8) and the logic control unit is configured so as to operate the second power means in such a way as to vary the processing depth according to the rotation angle of the grinding wheel (4).
