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.

There is provided a film dispenser including a pre-stretch assembly, a dancer bar and a dancer bar control assembly. In response to a variation of a film feed requirement, the dancer bar is movable over a displacement range between a first position and at least one second position. The dancer bar is in the first position when a tension in the material web is below a threshold and in the at least one second position when the tension in the material web is equal to or above the threshold. The dancer bar control assembly is connected to the pre-stretch assembly and the dancer bar and is configured to bias the dancer bar with a constant force over the displacement range, monitor a displacement of the dancer bar and generate a speed command based thereon, and send the speed command to a motor to adjust the film delivery speed.

A web handling system is described, including a plurality of web handling controllers and a web handling process logic controller networked to form a ring network. A processor of the web handling process logic controller being configured to determine whether a fault exists within the ring network, and responsive to determining that a fault exists within the ring network, to generate and send signals throughout the ring network to switch the configuration of the ring network to at least one linear network.

A sheet storage apparatus and a printing apparatus include simplified mechanisms for supporting a sheet and for guiding the sheet. A sheet storage device that can store a sheet discharged from a discharge port of a printing apparatus includes multiple flappers provided below the discharge port and arranged in a width direction of the sheet, each flapper being rotatable between a first posture in which the sheet discharged from the discharge port is guided downward in a gravitational direction by using a first surface, and a second posture in which the sheet is supported by using a second surface being different from the first surface; and a connecting unit which connects the plurality of flappers to one another.

A system for deploying a coil of spoolable pipe from a vessel includes a first tower configured to move longitudinally and transversely along a first track coupled to the vessel, a second tower configured to move longitudinally along a second track coupled to the vessel, and a coil drum assembly coupled to the first tower. The first tower is configured to insert the coil drum assembly transversely into an interior channel of the coil when the coil drum assembly is in a retracted position, the coil drum assembly is configured to support the coil when the coil drum assembly is in an extended position and rotate during deployment of the spoolable pipe, and the first tower and the second tower are configured to move the coil drum assembly vertically.

According to an example aspect of the present invention, there is provided a method, comprising: controlling suction with predetermined force in a known measurement area to a moving cardboard or paper web in a manufacturing process, detecting on-line measurement information on deviation of the moving cardboard or paper web in the manufacturing process caused by the suction with predetermined force in the known measurement area, and determining elastic modulus of the moving cardboard or paper web in the manufacturing process on the basis of the measured deviation.

The present invention relates to a method of stacking individual sheets and a stacking machine for handling individual sheets, the stacking machine comprising a frame assembly (13) including support columns (711, 811) for supporting the delivery station (70), the transfer station (80) and the elevation station (82). The delivery station has a delivery table and the transfer station including a handling arm (85) is movable from a first position above the delivery table to a second position above the elevation station. The handling arm includes a holding member (86) for contacting the sheets individually and transferring the sheets individually from the delivery table to the elevation station and releasing the sheets individually at the elevation station. The elevation station has a platform for collecting the individual sheets and the platform is moved vertically from a first level to a second level for allowing the sheets to be stacked on top of the one another.

Provided is a medium supply device including a spindle that supports a medium having a roll shape, a supplying portion that supplies the medium supported by the spindle toward outside, a plurality of support rollers that support the medium in positions between the spindle and the supplying portion, a moving roller that, in a contact position between the support rollers, is capable of coming into contact with a bridging medium extending across the support rollers in a state where a load is applied to the bridging medium and that is capable of moving from the contact position to a non-contact position of non-contact with the bridging medium, and a moving mechanism configured to move the moving roller from the contact position to the non-contact position.

The invention discloses a tensioner comprising a belt shaft, a first bracket and a second bracket, a belt shaft hole is provided at a front end of the first bracket, the belt shaft passes through the hole and is hinged with the first bracket; a surface of the belt shaft is provided with a ratchet fixedly connected thereto and gaskets provided on two sides of the ratchet; one end of the second bracket is provided with a clamping portion, the clamping portion clamps two ends of the belt shaft and protrudes outwardly to form an accommodating cavity, balls are provided inside the accommodation cavity, and the balls are installed on an outer gasket of the belt shaft. The plastic gaskets greatly reduce the friction between the ratchet and the bracket, the balls provide a certain degree of freedom for the belt shaft to prevent the belt shaft from jamming.
