A vacuum belt has perforations between belt edges. Some perforations in the vacuum belt are arranged in a pattern. The vacuum belt is positioned adjacent the media supply in a location to move sheets of the print media from the media supply. A light sensor is positioned in a location to detect light passing through the vacuum belt. The light sensor detects a portion of the vacuum belt as limited by an aperture area of the vacuum belt, and the pattern of perforations, and the size and location of the aperture area of the vacuum belt causes the signal output by the light sensor to be constant when the sheets are outside the aperture area of the vacuum belt.

A device for the surface treatment of a substrate including a transport device, a vacuum suction device, a corona device and a coating device, is described. The transport device is formed as a conveyor belt. The conveyor belt is formed as a vacuum suction belt of the vacuum suction device, and the conveyor belt is formed as a counter electrode of the corona device.

A medium transporting apparatus includes an endless conveyor belt having an outer surface to which a sheet P adheres, at least two rollers, which are a first roller and a second roller, around which the conveyor belt extends. The second roller is located downstream of the first roller in a medium transporting direction. The medium transporting apparatus also includes a backing plate that supports an inner surface of the conveyor belt at a position between the first roller and the second roller. In the medium transporting apparatus, the backing plate includes a hollow-containing portion that is formed at an upstream end of the backing plate in the medium transporting direction. The hollow-containing portion has a plurality of hollows formed therein in a width direction that intersects the medium transporting direction. The plurality of hollows are formed in a support surface that supports the conveyor belt.

A digital printing device, comprising a suction transport means (1). The suction transport means (1) comprises a transport belt (11) used for transporting a sheet material. At least one first suction box (14), which is used for sucking the sheet material on the transport belt (11) by means of negative pressure during transport, is provided in the space defined by the transport belt (11). Multiple first suction holes in communication with the first suction box (14) are provided on the transport belt (11). At least one side of the first suction box (14) is provided with a movable door (15) which moves in a direction perpendicular to the transport direction to make the first suction box (14) fit the sheet material to maintain a negative pressure state. Using the transport belt (11) during printing, the digital printing device avoids the problem of poor registration accuracy, and improves the printing effect.

Aspects of automated fabric picking are described. In one embodiment, a system includes a textile cutter including a tabletop upon which textile panels can be cut out from a textile sheet, a textile panel picker, and a computing device. The textile panel picker includes a flexible transport tube, a transport tube transfer arm to position the flexible transport tube over the tabletop and the textile panels, a textile hopper to collect the textile panels, and a pneumatic pump assembly to evacuate air from the textile hopper and through the flexible transport tube. The computing device identifies and tracks the textile panels on the tabletop, directs the transport tube transfer arm to position the flexible transport tube over the textile panels, and directs the pneumatic pump assembly to generate suction to pull the textile panels through the flexible transport tube and into the textile hopper.

An endless conveyer belt is stretched between drive and idle rollers. A carriage is arranged so as to reciprocate along the endless conveyer belt. A suction box is arranged between upper and lower belt portions of the endless conveyer belt and fixed to the carriage. A stopper plate is fixed to the carriage and extends across a conveyer surface and upward from the conveyer surface. A conveyance roller pair is arranged at the upstream end of the conveyer surface. A region of the conveyer surface from a stopper plate to the upstream end u forms a sheet accumulation area. A cover sheet covers a region upstream of the suction box in the sheet accumulation area. The cover sheet is subjected to tension in the longitudinal direction by a winding-type constant force plate spring and continually tensed spaced apart from the endless conveyer belt.

A roller which has woven fabric at a surface thereof and which is employed in an apparatus permitting achievement of conservation of resources, conservation of energy. Roller 1 provided with covering 3 includes woven fabric at its surface is idler means or drive means for conveying, supply, of an object, means for air cooling or drying a moving object, rotating means making use of suction of an object, or is for cleaning a contact surface to which roller 1 is opposed, and has at the surface woven fabric 2 with variation or combination of weave pattern(s). The woven fabric 2 includes weaving in a linear pattern of bands or different patterns. It also has open holes including lattice-like gaps 8 or a rectangular pattern 6 for control of air permeability formed from weft yarn 25 and warp yarn 26.

Embodiments of a system and method for shingulating, singulating, and synchronizing articles in an article feeder system are disclosed. The article feeder system may include a shingulating device configured to receive a stack of articles and to produce a positively lapped stack of articles, a plurality of picking devices configured to pick one or more articles from the positively lapped stack of articles and to produce one or more singulated articles, and one or more synchronization devices configured to deliver the one or more singulated articles to one or more sorter windows.

A recording medium conveyance device of an inkjet recording device includes a belt-form member, two conveyance rollers, a driver, a supporting board, a suction unit, and a guide roller. The recording medium is placed on the outer circumferential surface of the belt-form member. The belt-form member is pulled over the two conveyance rollers which cause the belt-form member to circulate. The driver causes at least one of the two conveyance rollers to rotate. The supporting board supports the inner circumferential surface of the belt-form member on a plane. The suction unit pulls the recording medium placed on the belt-form member to the outer circumferential surface of the belt-form member. The guide roller is arranged between at least one of the two conveyance rollers and the supporting board and supports the inner circumferential surface of the belt-form member.
