Abstract: 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.

Abstract: A sheet transport system for moving a sheet in a transport direction while adjusting a position of the sheet in a lateral direction normal to the transport direction to a target position, includes first and second pinch roller sets spaced apart from one another in the transport direction, each pinch roller set including two pairs of pinch rollers spaced apart from one another in the lateral direction, each pair forming a nip for pinching and driving the sheet with an individually controllable speed; a detection system for detecting a position of the sheet in the lateral direction while the sheet is pinched by the first pinch roller set; and a control system configured for carrying out the following actions: by controlling the speeds of the pinch rollers of the first pinch roller set before the sheet has reached the second pinch roller set, rotating the sheet by a first rotation angle for adjusting a given reference point on a leading part of the sheet to its target position; and when the sheet has left the fi

Abstract: A support structure defining a flat support surface for supporting a web material includes a number of beams, each having a cross-section elongated in a first direction normal to the support surface. The beams have a ruler edge extending in a second direction in parallel with the support surface, which is defined by the ruler edges. The support structure includes a number of adjustment mechanisms for adjusting the positions of the ruler edges in the first direction. Each beam has a base part and a ruler part, the ruler part defining the ruler edge and being connected to the base part by at least three adjustment mechanisms distributed over the length of the beam. Each adjustment mechanism includes a lever that is pivotable relative to the base part about a fixed fulcrum, is connected to the ruler part, and has an adjustment arm with an adjustable free end.

Abstract: Method for holding substrates on a flatbed printing system. After positioning the substrates on the substrate support surface, a leak air area not covered by the substrates is covered by positioning a flexible cover device at least over the leak air area, and preferably over the substrates as well. Thereby, air flow through the through-holes is prevented. An under-pressure is then applied to the through-holes, sucking the substrates against the substrate support surface. The flexible cover device is then withdrawn to expose the substrate for printing while the under-pressure is maintained. It was found that despite the additional amount of air passing through the through-holes uncovered by the withdrawal of the flexible cover device, the under-pressure surprisingly remained sufficient to properly hold the substrates for printing. An additional advantage is that the cover device may be applied easily and rapidly over the leak air area and substrates at once.
