An apparatus for cleaning a felt in a system for producing a paper web has a device for introducing a cleaning liquid into the felt and at least one following suction device in the direction of movement of the felt and having a vacuum duct, through which the cleaning liquid is suctioned out of the felt. The suction device between the vacuum duct and the felt is formed with suction ducts, through which the cleaning liquid in the felt is suctioned away. At least one of the suction ducts is assigned an inflatable valve element. In the inflated state of the valve element the suction duct is closed and in its ventilated state the suction duct is opened.

A recording-material-transporting device includes a suction unit that suctions a recording material included in a recording-material stack from above, the suction unit including a movable member that moves upward when pushed from below by the recording material moving upward with the suction, the suction unit being movable in an intersecting direction intersecting a vertical direction and moving the suctioned recording material in the intersecting direction, at least a part of the movable member serving as an outside advancing part that advances to an outside of a perimeter of the recording-material stack with the movement of the suction unit in the intersecting direction; and a restricting part that restricts a downward movement of the outside advancing part when the outside advancing part is free of support by the recording material from below.

Machine for feeding flatwork articles to an ironer-dryer machine, the machine including loading posts (1) with a load conveyor (2) for loading flatwork articles (53); one pair of transferring grippers (6) at each loading post (1), two or more spreading grippers (7) at a pickup station movable along one transverse guide (8); an outgoing feed conveyor (9) to transfer the flatwork article (53); and a vacuum chamber (44) below the spreading grippers (7) and below conveyor (9). The spreading grippers (7) are independent of each other, to spread a flatwork article (53) at several different zones with regard to the conveyor (9), operative in one or more lanes. A suction entrance (45) of vacuum chamber (44) has associated movable separating blades (59) temporally preventing insertion of a spread flatwork article (53) into vacuum chamber (44) and a controller coordinates the movements of the transferring grippers (6), spreading grippers (7) and separating blades (59).

System and method of laser processing a section of web, or “strip” in a “step and repeat” manner while doing so with a continuously moving web during laser processing. The combination of continuous laser processing with a step and repeat manner of cutting parts from the strip, increases throughput for parts. The method includes retracting and indexing a web between passes of continuous laser processing of the web of material and alternating laser processing between two webs in a dual web system further increases throughput results from laser processing.

The invention relates to a release liner removal apparatus, comprising at least one release liner removal device for removing at least one release liner from at least one adhesive piece arranged on a material web, at least one support body which supports the at least one release liner removal device, and at least one guide body which is arranged adjacent to the at least one release liner removal device at least during the removal of the at least one release liner and which serves for guiding the material web.

The invention relates to a plant having at least one material roll preparation arrangement for bringing a material roll carrying a material web to be drawn in into a defined initial situation, and having at least one material web working/processing arrangement, in particular material web dispensing arrangement, in particular material web unrolling arrangement, in particular material web splicing arrangement, which material web working/processing arrangement is capable, owing to the defined initial situation of the material roll, of receiving the material roll in automated fashion and preferably receiving the material web in automated fashion and/or preparing the material web in automated fashion.

A low cost and low air resistance belt support structure for an endless belt conveyor of an inkjet printer can be achieved with the belt support structure being provided over a suction chamber. The belt support structure includes a plurality of longitudinal, narrow support beams positioned spaced apart from one another and parallel to one another in a transport direction of the belt to define a flat support plane for the belt. The support beams provides a relatively small contact area with the belt, which results in low friction The support beams further allow for a relatively large open area between them to achieve a low air resistance.

A sheet conveyor includes a conveyance belt configured to convey a sheet on a first surface of the conveyance belt in a conveyance direction, a suction device configured to suck the sheet onto the conveyance belt via the conveyance belt, and multiple supports between the conveyance belt and the suction device in a vertical direction, the multiple supports configured to support a second surface of the conveyance belt. A longitudinal direction of each of the multiple supports is parallel to a direction intersecting the conveyance direction, and the multiple supports are arrayed in the conveyance direction.

A method and apparatus for preparing edges of reels of web material, where a reel is held with its axis horizontal; a manipulator applies a first adhesive element on an outer surface of the reel; a gripping member picks up the first adhesive element and forms a loop; and a cutting device transversely cuts the web material at the loop. A section of web material with a length equal to or greater than a circumference of the reel is unwound from the reel; a second adhesive element is applied on an outer surface or on an inner surface of the web material; and a scrap portion of the web material is cut and discarded by a suction device.

A belt conveyance device includes an endless belt, a duct having a suction port, and a rectifier inside the duct. The duct is surrounded by an inner circumferential surface of the endless belt. The rectifier extends in a width direction of the endless belt perpendicular to a direction of conveyance by the endless belt.
