The present invention relates to a machine for producing multi-layer cardboard or paper, or a machine for either printing or converting, starting from a reel of paper, cardboard or other material. In general, the invention can be applied to machines wherein a reel of different materials is unwound and which requires a contrast system to regulate the tensioning of the ribbon. In particular, the invention relates to a system for braking said reel.

In particular, the invention relates to a braking system (2) for a support member (1) of a reel (B), for example, a reel of paper in a machine for producing cardboard or corrugated cardboard, wherein said braking system (2) comprises a motor-generator device (8) and a mechanical brake device (9) arranged coaxially.

A brake is provided for an idler roll (10) of a fiber web machine, in particular of a slitter-winder, which idler roll (10) has an outer shell surface (13). The brake (20) is located outside the outer shell surface (13) of the idler roll (10) in close vicinity of the idler roll (10) in a non-contacting position. The brake (20) has a permanent magnet (25), which is configured to be moved from non-braking position to a braking position and vice versa by an actuator or cylinder (35, 45).

The invention relates to a brake device (1) for braking an elongate medium (10) that is to be wound up, having an energy recovery device (16a; 16b; 16c; 16d) which is coupled to the at least one braking roller (14a) and which is designed to act on the at least one braking roller (14a) with a predefined braking moment in order to brake the elongate medium (10) that is to be wound up. The invention furthermore relates to a method for operating a brake device (1) for braking an elongate medium (10) that is to be wound up.

A lottery ticket dispensing unit includes at least one ticket compartment and a separation module that has a drive roller and an opposed idler roller, with a motor geared to the drive roller. An automatic separator device is provided, wherein the drive roller conveys a leading lottery ticket to a separation position such that a line between the leading ticket and an adjacent ticket is presented to the separator device. The separator device includes a shuttle that travels in a linear path along the line, the shuttle having a head that engages and separates the leading ticket from the adjacent ticket along the line. A bi-directional drive mechanism moves the shuttle back and forth along the linear path.

A lottery ticket dispensing unit includes at least one ticket compartment and a separation module that has a drive roller and an opposed idler roller. A motor is geared to the drive roller and is switchable between a convey mode wherein the drive roller engages and conveys a leading ticket to a separation position and a brake mode wherein the motor provides a reverse retarding force to the drive roller to brake the drive roller against an attempted reeling of the lottery tickets. from the dispensing unit. A controller switches the motor between the convey and brakes modes such that in the brake mode, power to the motor is interrupted and windings in the motor are short-circuited.

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).

A brake is provided for an idler roll (10) of a fiber web machine, in particular of a slitter-winder, which idler roll (10) has an outer shell surface (13). The brake (20) is located outside the outer shell surface (13) of the idler roll (10) in close vicinity of the idler roll (10) in a non-contacting position.
