Abstract: An expansible chuck for holding hollow cylindrical cores used for winding and unwinding sheet material. A portion of the chuck body nearest the flange is stepped up so that the diameter of the chuck near the flange is slightly larger than the diameter of the rest of the chuck. The stepped up portion centers the chuck within the core which helps the expanding elements to uniformly grip the core.

Abstract: Rolling assembly for packaging web material in a roll having a base member with concave arcuate feed surface defining an upwardly-extending ramp, first intermediate member movably coupled to base member, and top member moveably coupled to at least one of base member or first intermediate member, top member having a concave arcuate pressure surface facing feed surface of base member. The base member, first intermediate member and top member collectively forming an iris with a feed space, the iris moveable between a first condition and a second condition, and configured to receive web material along the feed surface and direct the web material upwardly toward the top member to form a roll within the feed space, the iris moving toward a second condition as the roll of web material increases in cross dimension against the pressure surface of the top member.

Abstract: A winding machine (10) for winding and/or unwinding band-shaped or strip-like material (12) has at least one rotary plate (16), which is arranged on a pivot arm (24) and can be driven by means of at least two opposite coupling elements (20, 22), at least one coupling element (20) being associated with the rotary plate (16), and the rotary plate (16) being transferrable by means of a pivot device (30) between at least one decoupled state and at least one coupled state. Because the coupling elements (20, 22) can be positioned opposite one another in a coupling position in a sensor-based manner, this allows a coupling process which is as wear-free as possible.

Abstract: A winding machine (10) is disclosed comprising at least one reel holder (12) mounted on a supporting frame (11) and rotatable around its own axis (13), and a plurality of reels (1-4) mounted on the holder (12) and integrally rotatable therewith so that at least one first reel (1) is in at least one operative winding position of a bobbin (5). It is further described a respective method for the in-line winding of bobbins (5) of stretch film (6), comprising the steps of rotating a core (7) on a reel (1) in an operative winding position to wind the film (6) onto the core (7), positioning a contact roll (15a) in at least one proximal contacting position in which it contacts the winding bobbin (5) for facilitating the peripheral winding of the stretch film (6) on the core (7), bringing the reel (1) from the operative winding position of the bobbin (5) to an operative unloading position of the bobbin, positioning an accompanying roll (15b) in at least one proximal contacting position in which it contacts the bobbin (5) for facilitating the peripheral winding of the stretch film (6) on the bobbin (7), transversally cutting the stretch film (6) and unloading the bobbin (5). The movement of the contact roll (15a) and the accompanying roll (15b) is carried out by means of electric actuators (18a, 18b).

Abstract: A safety chuck mounted to equipment that process web material is provided. The safety chuck is provided with a die spring connecting a moveable jaw with a spindle, said spring urging the moveable jaw into a fully closed position. A number of magnets mounted on a mounting flange will engage the moveable jaw, overcoming the spring's force and holding the moveable jaw in a fully open position. Rotation of the spindle releases the magnets allowing the spring to force the moveable jaw back into a fully closed position.
