Method and apparatus for producing and drawing-off a web-shaped product (2) with a production machine (1) and two clamp carriers (7.1, 7.2) with clamps (10.1, 10.2). The clamp carriers (7.1, 7.2) are driven moving back and forth parallel to a drawing-off direction of the web-shaped product (2). The clamp carriers (7.1, 7.2) are respectively drivable with a pair of drive spindles (14.1, 14.2), which are arranged in such a manner so that the web center of the web-shaped product (2) within the apparatus (6) extends in an area between the two drive spindles (14.1, 14.2) of the respective clamp carrier (7.1, 7.2). The method is characterized in that the web-shaped product (2) is produced with successive main sections (4.1, 4.2, 4.3, 4.4) and auxiliary sections (3.1, 3.2, 3.3, 3.4, 3.5), and that the clamps (10) are actuated in such a manner so that the opening and closing of the clamps (10) takes place only in the time segments of the production in which an auxiliary section (3.1, 3.2, 3.3, 3.4, 3.5) of the web-shaped product (2) is being produced.

A winding machine (10) is disclosed comprising at least one reel holder (12) mounted on a supporting frame (11) and N 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).

A plunger of a solenoid includes a pin member that moves in a groove portion of a link member in association with a displacement operation, the solenoid regulates the posture of a path switching member in a suction state, a contact surface that is an inner surface of the groove portion and with which the pin member comes into contact when the plunger moves in a suction direction is formed in a non-linear shape to have a first region extending in a first direction and a second region extending in a second direction intersecting the first direction, and an angle formed by the suction direction and the second direction is smaller than an angle formed by the suction direction and the first direction.

A scanner with the automatic expanding output tray includes a mechanical body, a first output tray, a second output tray, an extending output tray, an extending torsion spring, a limiting element and a unidirectional actuator. The first output tray has a starting end pivotally connected to a rear of the mechanical body, and a connecting end. The second output tray has a pivoting end pivoted at the connecting end, and a terminal end. The extending output tray is pivotally connected to the second output tray. The extending torsion spring is mounted between the extending output tray and the second output tray. The limiting element is pivotally connected to the second output tray. The unidirectional actuator is mounted between the limiting element and the first output tray.
