The splicing device for splicing a trailing edge of a first web material to a leading edge of a second web material includes members defining a feed path of the web material. The device also includes a first cutting member and a second cutting member, cooperating with the first cutting member. One of the two cutting members is provided with a movement transverse to the feed path of the web material, to move the cutting member from an operating position, in which it is in front of the other cutting member, to an idle position, withdrawn with respect to the feed path of the web material.

Provided is a roller with pressure sensor. The roller includes a pressure sensor mounted to the roller. The pressure sensor includes a plurality of pressure sensing units distributed on a thin film. The pressure sensing units are electrically connected to each other with a metal wire but not in contact with each other. Also provided is a roll-to-roll device, which includes a roller mechanism and a pressure sensor.

Disclosed is a buffer system for buffering a length of a strip, wherein the buffer system includes a buffer member, a buffer drive and a control unit, wherein the control unit is configured for receiving control data having information indicative of an input amount of the strip at the input side and information indicative of an output amount of the strip at the output side, and for generating, based on said control data, a computed value indicative of a theoretical length of the strip in the buffer system between the input side and the output side, wherein the control unit is further configured for positioning the buffer member at a buffer position based on the computed value. The disclosure also provides a method for buffering a length of a strip, and a computer program product.

A splice arrangement includes an unwinding arrangement for unwinding a finite first material web from a first material roll or a finite second material web from a second material roll, a braking arrangement for applying a braking force to the unwinding arrangement and/or the finite material web being unwound, a connection arrangement for connecting the finite material webs to form an endless material web, a storage trolley for the uninterrupted conveying of the endless material web, at least one material web tension-influencing device arranged before the storage trolley, and an actuation device, which is in signal connection with the at least one material web tension-influencing device for actuating the same.

Described is a device for feeding and accumulating film (2) made of plastic material wound on a reel to a bagging machine (4), comprising a frame (9), means for supporting at least one reel (3) of film (2) made of plastic material supported by the frame (9), a first and a second group (G1, G2) of rollers for redirecting the film (2) made of plastic material, the rollers of the first and second group (G1, G2) being arranged in two respective rows parallel to each other, the film (2) being designed to be wound alternatively on the rollers of the two groups (G1, G2) forming a plurality of loops.

A film intermittent carrying device: includes a film delivering mechanism, a delivering and accumulating mechanism, accumulating the film and discharging the film, a winding and accumulating mechanism accumulating the film while discharging in an amount corresponding to an amount of the film discharged, and a film winding mechanism taking-up the film constantly. The delivering and accumulating mechanism includes first and second fixed rollers, an upstream-side movable roller moving to pass through a middle position between the first and second fixed rollers, and an upstream-side friction preventive unit configured to reduce a friction between the film and the upstream-side movable roller. The winding and accumulating mechanism includes third and fourth fixed rollers, and a downstream-side movable roller moving to pass through the middle position between the third and fourth fixed rollers, and a downstream-side friction preventive unit configured to reduce a friction between the film and the downstream-side movable roller.

Provided is a roller with pressure sensor. The roller includes a pressure sensor mounted to the roller. The pressure sensor includes a plurality of pressure sensing units distributed on a thin film. The pressure sensing units are electrically connected to each other with a metal wire but not in contact with each other. Also provided is a roll-to-roll device, which includes a roller mechanism and a pressure sensor.

There is provided a process liquid coating apparatus comprising: a recording medium conveyance unit configured to convey a recording medium; a coating roller configured to rotate in accordance with the conveyed recording medium to apply process liquid on a surface of the recording medium; a pressure roller configured to cause the coating roller to apply the process liquid on the surface of the recording medium by forming an abutment part for nipping and pressing the recording medium with the coating roller; and a winding member configured to form a bent conveyance path along which the recording medium is bent with respect to a conveyance direction so that the recording medium is wound around the surface of the pressure roller, wherein the winding member is disposed adjacent to the pressure roller.

A web handling system is disclosed. The web handling system includes first dancer rollers coupled to engage and move a web of a print medium in a forward and backward direction upon stopping a printing operation and allow forward motion during the printing operation.

A method and system for joining strips of battery grid comprises feeding a first strip of battery grid into a processing station at a predetermined feed rate, and progressively increasing the path length of the first strip until a target path length is reached. When the end of the first strip is reached, the path length of the first strip is progressively decreased while holding the end of the first strip. The rate of decrease allows the first strip to continue to be delivered into the processing station at the predetermined feed rate. A second strip is advanced from a second feed supply to a position adjacent the end of the first strip. The adjacent ends are joined by laser welding. The decreasing of the path length is stopped, and the second strip of battery grid is fed into the processing station at the predetermined feed rate.
