Abstract: A large-scale printhead is made up of rows of styli patterned onto thin glass substrates sandwiched together between rugged support substrates, in which a series of thin glass substrate sections are internally butted one to the other. Fabrication of multiple rows of elements is accomplished by stacking the delicate styli-bearing substrates on an associated rugged substrate. In a preferred embodiment, all glass substrates are utilized, with the transparency of the glass permitting accurate alignment of the styli or nibs. The use of glass substrates also increases the wear resistance of the completed printhead. A specialized bus matrix permits reduction in the width of the substrates carrying the styli, with the bus structure being formed on a single side of the substrate carrying the styli, such that thru-holes need not be provided through the thin substrates.

Abstract: High strength composite tape is prepared for laying in side-by-side strips upon a work surface by precutting the strips to a predetermined length and mounting the strips upon a carrier belt in longitudinally spaced relation to one another, so that the pressure foot of the machine applying the tape to a work surface may press to the end of one tape strip without pressing the end of the following tape strip. Improved laying of the tape is achieved by stretching a strip of tape entirely across the area on which the tape is to be laid before pressing any part of the tape against the work surface, and then pressing the tape against the surface while the tape is stretched across and adjacent the work surface. The tape is held and stretched across the work surface on supply and take up reels on opposite sides of the work surface, so that the reels need not move along the tape with the moving pressure foot.

Abstract: To eliminate the necessity for stapling together web portions which are derived, for example, from a rotary printing machine, and superimposed, and which should be joined together, one of the web portions is deflected in a separate path and has a strip of adhesive applied transversely to the direction of movement, for example by passing the web portion between a pair of rollers, one of which has adhesive applied thereto.
