A tension applying device is attached to a sheet conveyance device. The sheet conveyance device includes a feeding roller for feeding a continuous-form sheet and a winding roller for winding the continuous-form sheet fed from the feeding roller. The tension applying device applies tension to the continuous-form sheet between the feeding roller and the winding roller. The tension applying device includes a guide rail, a slider, a tension bar, and an angle adjustment mechanism. The guide rail is inclined downward toward a continuous-form sheet. The slider slides along the guide rail. The tension bar is supported by the slider and brought into pressure contact with the continuous-form sheet by weight of the slider. The angle adjustment mechanism adjusts an inclination angle of the guide rail with respect to a horizontal direction.

Provided is an adhesive film production apparatus for producing an adhesive film having an adhesive layer on a base material layer, the adhesive layer having an elastic modulus at 230° C. of 1 MPa or greater and having a glass transition temperature higher than normal temperature, the adhesive film production apparatus including a feeding roller; a cutting part; and a plurality of winding cores, wherein the raw film of the adhesive film is wound on the feeding roller such that the adhesive layer faces outward, and wherein in the conveyance path of the adhesive film traveling from the cutting part toward the winding core, the number of times of the adhesive layer of the adhesive film bending in a convex manner is set to be equal to or more than the number of times of the adhesive layer bending in a concave manner.

A sheet conveyance apparatus includes an acquisition unit that acquires information indicating a peeling position where a protective film is peeled off a sheet, and a control unit that controls a roll device based on the information and moves the peeling position.

A dunnage conversion system for making a coil of dunnage from a sheet stock includes a coiler, a movable dancer upstream of the coiler and interposed in a path of the sheet stock, and a controller communicatively coupled to each of the coiler and the movable dancer. The coiler is configured to wind the sheet stock, and the controller is configured to control the speed of the coiler based on the position of the movable dancer to control tension of the sheet stock upstream of the coiler. The sheet stock drawn about the movable dancer may be a slit-sheet stock having a plurality of slits configured to expand under tension applied in a feed direction. The controller may be configured to control expansion of the slit-sheet stock upstream of the coiler allowing conversion of the sheet stock into a coil of relatively less dense dunnage prior to or during winding.

According to an example, a method to wind media in an output roller downstream a media advance engine comprises advancing a medium for a determined medium length, collecting a first portion of the determined medium length at a first speed by rotating the output roller in a winding direction, and collecting a second portion of the determined medium length by rotating the output roller in a winding direction at a second speed, wherein the first speed is greater than the second speed.

A system (300) is provided having a printer (4) to print printing liquid onto a web (6) of media (8). The system (300) has a winding roller (10) on which to roll the web (6) of media (8) after printing. A tensioner (12) to vary the tension in a portion (14) of the web (6) of media (8) is also provided. The portion (14) is a portion of web which is being rolled onto the winding roller (10). Also provided is controller (16) to control the tensioner (12) to vary the tension based on the time taken for the printed printing liquid on the web (6) of media (8) to dry.

A winding device includes a mandrel for winding the electrode laminate, the mandrel having a first end and a second end opposite the first end; a first rotation driver located at the first end of the mandrel to rotate the mandrel; and a second rotation driver located at the second end of the mandrel to rotate the mandrel.

A control device of a transport device includes a control unit configured to control a roll motor for rotating a first rotary shaft on which a medium is held and a transport motor for rotating a first driving roller, a tension detection unit configured to derive, for each tension detection cycle, a detected tension value of a tension applied to a tension adjustment portion of the medium, and a tension F/B unit configured to calculate a tension F/B correction amount by feedback control based on a deviation between a target tension and the detected tension value. The control unit is configured to calculate a driving force by the roll motor based on the tension F/B correction amount, and control the roll motor based on the driving force.

Methods and apparatus provide for sourcing a glass web, the glass web having a length and a width transverse to the length; continuously moving the glass web from the source to a destination in a transport direction along the length of the glass web; and cutting the glass web at a cutting zone into at least first and second glass ribbons as the glass web is moved from the source to the destination, the first glass ribbon having a first width and the second glass ribbon having a second width, where the first and second widths are not equal.

A sensing device is for sensing an outer surface of a roll of material. An infrared (IR) laser source is configured to direct IR laser radiation to the outer surface of the roll of material. A single photon avalanche diode (SPAD) detector is configured to receive reflected IR laser radiation from the outer surface of the roll of material. A controller is coupled to the IR laser source and the SPAD detector to determine a distance to the outer surface of the roll of material based upon a time-of-flight of the IR laser radiation.
