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.

Apparatus and methods for web tension control are provided. In an example, an apparatus can include a tension beam configured to deflect in a predictive manner when under a force load, a first shaft directly coupled to the tension beam and configured to mechanically interface with a torque device, a second shaft directly coupled to the tension beam opposite the first shaft and configured to interface with a structural member of a web machine, and a strain gauge coupled to the tension beam and configured to provide an electrical representation of the force load.

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).

An apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, comprising an output device which is configured to eject at least one material web into the cutting region, wherein the output device comprises at least one driven feed roll and at least one counter-unit which forms a feed gap for the material web together with the feed roll.

The invention relates to an apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, having a material store; and having a removal device which is configured for a removal of a material web from the material store, wherein a loop store in which the material web forms a loop is provided for the material web.

A system for braking rotational movement of at least one beam is disclosed. The system can comprise a frame and at least one beam rotatably supported on the frame. Each beam of the at least one beam can comprise at least one sheave groove on at least one longitudinal end. A rope can have a first end and a second end. Each of the first end and second end can be fixedly coupled to the frame. The rope can be received within a portion of at least one of the at least one sheave groove of each beam. A tensioning assembly can be configured to selectively cause a predetermined braking tension in the rope.
