A tension brake assembly includes a frame, a plurality of brake pad assemblies, and a hub configured to be coupled to a rotating component. The hub includes a plurality of drive pins adjacent an annular wall. A rotor engages the plurality of drive pins such that rotation of the hub causes rotation of the rotor while permitting axial movement relative to the annular wall. The rotor has friction surfaces for engagement with the brake pad assemblies. An actuator is provided. Movement of the actuator in a first direction moves the friction components together in the axial direction to increase friction exerted by the tension brake assembly. Movement of the actuator in a second direction moves the friction components away from one another in the axial direction to decrease friction exerted by the tension brake assembly.

A system for supporting a reel of stamping foil (2) that is mounted rotatably, includes: two flanges (9, 9) connected to the shaft of the reel (2, 2) that is positioned between the flanges, each flange having a rotary shaft extending outward of the reel; two end walls (7, 7) mounted spaced apart on a guide surface (3), each wall end having at least one upwardly oriented notch (10, 10) arranged to receive the shaft of each flange (9, 9); and a brake (13) which cooperates with and slows the rotation of the reel (2).

Apparatus and methods are provided for a self-contained tension control system. An example self-contained tension control system can include a brake system configured to provide tension friction to a web, a tension transducer to provide tension information indicative of tension of the web, a controller configured to receive the tension information, to compare the tension information to set point information, and to provide a command signal to the brake system, and an enclosure configured to enclose the brake system, the tension transducer, and the controller, the enclosure including a first web opening and a second web opening configured to allow the web to enter the enclosure and to pass through the enclosure to equipment downstream of the self-contained tension control system.

A clamping device (18) for supporting a reel having a tubular core is described. The clamping device (18) comprises a base body (20) with a mounting interface (22) for fixing the base body (20) on a machine frame. Additionally, it has a carrier body (36) configured for being placed inside the tubular core of the reel. The carrier body (36) is rotatably supported on the base body (20) such that the carrier body (36) can rotate with respect to the base body (20) about an axis (38) of rotation. Moreover, a plurality of clamping elements (42) are coupled with an actuation mechanism (76) such that the clamping elements (42) can selectively protrude from an outer circumference of the carrier body (36) and selectively be retracted to be at least flush with the outer circumference of the carrier body (36). Furthermore, a brake mechanism is arranged between the base body (20) and the carrier body (36) for selectively decelerating or blocking the rotation of the carrier body (36) with respect to the base body (20).

The braking device 1 includes two rotating members 10, 20 rotationally coupled with the reel, and a selection member 30 configured to cooperate by friction selectively with either one of the rotating members 10, 20 by moving the selection member to engage one or the other rotating member for friction braking.

A stencil printer includes a stencil, a material applicator to apply material on the stencil, and a stencil wiper assembly to selectively wipe the stencil. The stencil wiper assembly includes has a quick-change material module having a supply roller to receive a roll of material, a take-up roller to receive used material, a drive to move the material across the stencil from the supply roller to the take-up roller, and a controllable tension device configured to vary a tension of the material when driving the material from the supply roller to the take-up roller.

An example self-contained tension control system can include a brake system configured to provide tension friction to a web, a tension transducer to provide tension information indicative of tension of the web, a controller configured to receive the tension information, to compare the tension information to set point information, and to provide a command signal to the brake system, and an enclosure configured to enclose the brake system, the tension transducer, and the controller, the enclosure including a first web opening and a second web opening configured to allow the web to enter the enclosure and to pass through the enclosure to equipment downstream of the self-contained tension control system.

The negative pressure roll 1 is provided with a rotating shaft 2, an internal cylinder 3, an intermediate cylinder 4 and a multi-layered non-woven fabric laminated outer layer 5. Further, the rotating shaft 2 is a member at the center of rotation of the negative pressure roll 1 and connected to the internal cylinder 3 by a reinforcement circular disk 9. Still further, the internal cylinder 3 is formed in a tubular shape and rotates together with the rotating shaft 2. In addition, the rotating shaft 2 and the internal cylinder 3 correspond to a rotating main body. Further, the intermediate cylinder 4 is a cylindrical tubular material formed outside the internal cylinder 3 and rotates in association with the rotating shaft 2 and the internal cylinder 3. Still further, the multi-layered non-woven fabric laminated outer layer 5 is formed outside the intermediate cylinder 4 and given as a part at which the negative pressure roll 1 is in contact with the metal strip 13. The multi-layered non-woven fabric laminated outer layer 5 also rotates in association with the rotating shaft 2, the internal cylinder 3 and the intermediate cylinder 4. In addition, the negative pressure roll 1 is provided with a controller 6 for suppressing rotation of the negative pressure roll 1.
