An apparatus (1) serves to influence a running material web (2). To this end, the apparatus (1) has at least one adjustable roller (4), which deflects the material web (2). In order to improve the web running characteristics of the material web (2), the at least one roller (4) is adjustable by at least two degrees of freedom. Moreover, the at least one roller (4) is operatively connected to at least two actuators (17) such that at least one of the actuators (17) is assigned to each of the degrees of freedom.

A textile feed for a stepped operation digital textile printer, comprises a textile feeding mechanism, and a tension storage mechanism. The textile feeding mechanism feeds the textile in a forward direction onto the printer, but is at the same time mechanically connected to a tension storage mechanism which is tensioned by the forward feeding. At the end of the feed step, the tension storage mechanism releases respectively stored tension to cause the feed mechanism to briefly reverse feed, thereby to pull the textile taut and take up any slack caused by the feeding step. The textile is thus kept taut, to allow effective digital printing by the printer.

An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension-sensor and the edge-sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.

A device for introducing patterns by radiating a wound continuous substrate. The device provides patterning during continuous roll-to-roll movement without material slippage and with minimal distortion by providing a dancer roll between a processing drum and an unwinder roll on one side, and a winder roll on the other side, for tautly guiding the continuous substrate along a contact surface of at least half of the circumference of the processing drum in order to drive the continuous substrate without slippage. The dancer rolls are adapted to tautly guide the advancing substrate web and returning substrate web with a constant force, and an equilibrium is adjustable between a defined counterforce and the constant action of force on the dancer roll by a stabilization device, and is maintained constant by a controller based on measured deflections of the dancer roll by controlling the rotational speed of the unwinder and winder rolls.

The disclosure relates to a method of controlling tension of a media during printing. The media is tensioned by supporting a dancer bar coupled at a first end to a first dancer arm which moves about a first pivot. The tension is provided by resisting a net moment acting on the first dancer arm. The method comprises applying a first setting force to the first dancer arm to set the net moment acting on the first dancer arm and adjusting the first setting force to alter the net moment acting on the first dancer arm.

Tension rollers are each supported by, at one end regarding the axial direction thereof, a first supporting member fastened to a first tensional force adjusting member by fastening members and, at the other end regarding the axial direction thereof, a second supporting member fastened to a second tensional force adjusting member by fastening members. The first and second supporting members each include elongate insertion holes as insertion holes in which the fastening members are inserted. The first and second tensional force adjusting members each include elongate insertion holes as insertion holes in which the fastening members are inserted. The elongate insertion holes each extend in a direction intersecting the axial direction of the tension roller.

A method to advance a print medium, for example a flexible print medium, through a print zone of a printing device is described. A carrier is fed from a carrier supply. The carrier has an adhesive surface. A print medium is engaged with the adhesive surface of the carrier. The carrier with the engaged print medium is advanced to the print zone.

A system for forming glass rolls is provided. The system includes a glass ribbon supply system configured to supply a glass ribbon, a cutting system configured to cut the glass ribbon to a first portion and a second portion, a first glass winding system configured to wind the first portion of the glass ribbon to form a first glass roll, and a second glass winding system configured to wind the second portion of the glass ribbon to form a second glass roll.

A tensioning apparatus tensions straps, and in particular is configured to tension belts. In order to achieve good tensioning characteristics, the tensioning apparatus has a dynamically acting element, and by use of the dynamically acting element a transmission of force takes place indirectly in the case of the tensioning apparatus.

Manufacturing decorative panels by using a web-fed inkjet printer. During the feeding of the to-be-printed substrate, the tension of the substrate is controlled by a dancer unit (720) which includes a dancer roll (200), having a connector (120) on both side ends of said roll, and wherein both connectors (120) are connected to a pair of parallel guiders (110) for floating said roll along a floating path (210); and wherein the step of controlling comprises the step of moving one guider (110) of said pair of guiders (110) parallel to said floating path (210) whereby the dancer roll (200) is tilted.
