Abstract:
A page binding device for binding pages 11 from an inkjet printhead assembly 13. The device has an adhesive applicator 16 for applying adhesive to printed pages 11. The adhesive applicator 16 is adapted to eject adhesive onto the pages 11 as they are fed to the support tray. A page conveyor 12 for sequentially feeding pages 11 from the printhead assembly 13 to the support tray via the adhesive applicator 16. An air flow generator for generating an air flow 14 that prevents the pages 11 from contacting the adhesive applicator 16. Using an air cushion and a non-contact adhesive applicator avoids the paper buckling problems associated with contact adhesive applicators.
Abstract:
A system for printing, stacking and binding pages that has a drive system arranged to direct pages along a page path, a print station positioned on the page path, an adhesive station positioned downstream of the drive system, a support tray for receiving pages to be stacked, a vibrator interacting with the way so as to induce vibration therein and a press device adapted to apply a compressive force to the stack of pages.
Abstract:
A page binding support tray has vibratory page alignment. The tray has a floor having a lower-most corner at which two side walls of the tray converge. Previously edge-glued printed uniformly sized pages are received to form a stack upon the tray floor and vibration of the tray ensures that edges of the page bear against the side walls of the tray to align the pages prior to edge-pressing.
Abstract:
A cleaning sheet with a tacky surface coating is used to clean feed rollers in copying machines or similar equipment and similarly-coated cloths are used for the removal of particles from other surfaces to be cleaned. The cleaning articles are made by printing the tacky material on sheet material such as paper or cloth. Relatively thick layers of tacky material are applied quickly and economically by the use of a multi-stage printing press which builds up a thick layer from a plurality of thin layers.
Abstract:
Sheets to be coated with water-based coating material, for example a primer and a low adhesion backsize, are supplied from a feeder (1), in end-to-end overlapping relationship, to a dual coater (3) in which the sheets are coated individually on both sides. A sheet inserter (2) is provided, upstream of the dual coater, to insert sheets from a second supply into the sheets from the feeder (1). The dual coated sheets are dried as individual sheets or as a pseudo-web of overlapped sheets. The sheets are then overlapped, unless previously overlapped, and the direction of overlap changed, if necessary, to provide the trailing edge of each sheet on top of the leading edge of each succeeding sheet. The overlapped sheets are conveyed through an adhesive transfer station (7) where stripes (236) of at least partially dried adhesive are coated onto the dual coated sheets from a transfer belt (71).

Abstract:
The leader of a fresh flexible web of paper or the like is spliced to the trailing end of an expiring web by a row of uniting bands having coats of adhesive at both sides. Successive uniting bands of the row are peeled off a flexible carrier strip while being attached to one side of the leader. The expiring web is thereupon arrested and its trailing end is pressed against the uniting bands which already adhere to the leader of the fresh web. The peeling of uniting bands off the carrier strip takes place between a supply reel which stores convolutions of the carrier strip with a file of uniting bands on it, and a takeup reel for that portion of the carrier strip has been relieved of uniting bands. The number of uniting bands in a row depends upon the width of the fresh web and/or the expiring web. A carriage is movable back and forth transversely of the leader of the fresh web and carries an idler roller serving to peel a selected number of uniting bands off the carrier strip between the two reels.
Abstract:
In connection with an apparatus for putting paste on a moving printed paper web in strips at a right angle to the direction of motion of the web by moving the web between a pasting cylinder and a web support part on the other side of the web, one purpose of the invention is to make certain that the strips of paste may be put on at a high speed and to have such a design that the upkeep work on the apparatus is simple and may be done quickly. To make this possible, the pasting cylinder is made up of cylinder body and a paster roll placed within it so that a limited area of its outer face is uncovered by an axial slot in the outer face of the body. The paster roll has one or more wells stretching along it that are topped up with paste at a point within the pasting cylinder body, while the parts of the outer face of the roll between the wells are stripped and kept clear of the paste. The paster roll and the pasting cylinder body supporting it are turned about two separate, parallel axes with the axis of the roll moving round the axis of the body. The speeds of turning of the roll and the body are such that the sum thereof is equal to the speed of the web. At the point at which the web is acted upon by the roll its opposite side is supported by the support part that is in the form of a rail placed eccentrically on a turning shaft, the shaft being run at such a speed that the surface speed of the rail is equal to the speed of the web.
Abstract:
A transport system includes a transport device and a peeling device. The transport device includes: a transporting belt including an adhesive layer and configured to transport a medium affixed to the adhesive layer; a heating unit configured to be able to heat the adhesive layer; a driving unit configured to drive the transporting belt; and a control unit including a detector configured to detect a load of the driving unit, the control unit being configured to control the driving unit and the heating unit. The peeling device is configured to peel the medium from the transporting belt. The detector is configured to be able to detect the load of the driving unit when the medium is peeled from the transporting belt by the peeling device, and the control unit controls the heating unit on the basis of a detection result from the detector.
