Abstract: In a process and apparatus for winding a continuous webbing onto a windup spool wherein a webbing is fed from a supply direction to a rotatable feed drum, winding the webbing onto the feed drum, contacting the feed drum with a first windup spool for frictional rotational engagement therewith, when said first windup spool has a predetermined amount of webbing wound thereon ripping apart the webbing by forming a rip therein with the discharge pressure of a blast of air, and detaching the first windup spool from the engagement with the feed drum, the ripping of the webbing forming a leading edge at the rip in the webbing from the supply direction, winding the leading edge on a second windup spool, in that prior to the ripping, and at a location of the webbing when viewed from the supply direction before the second windup spool establishing rotational contact between the center of the webbing and a slitting wheel having a lateral slitting knife and an adhesive mounted thereon, rotating the slitting wheel in conta

Abstract: A thermal printer comprising a platen roller, a head mounting bracket having a thermal head attached thereto, a head holder for removably containing the head mounting bracket at a predetermined stationary position relative to the platen roller, and a pivotable support assembly pivotable about a supporting shaft, the pivotal support assembly housing the thermal head, head holder, and the head mounting bracket for pivotal movement of the thermal head, head holder, and the head mounting bracket toward and away from the platen roller, the head holder being a boxlike supporting frame having an opening at its bottom for fitting the head mounting bracket therethrough, the head mounting bracket and the supporting frame having respective front portions opposite to one another and being provided with engaging means for locating the head mounting bracket in the head holder at a predetermined fixed lateral position, the head mounting bracket and the supporting frame having respective rear portions with engaging means opp

Abstract: An apparatus for pressing a print head against a platen roll in a printer, which comprises a rotating profiled cam supporting the print head for moving the print head toward and away from the platen roll, a shaft in the center of and integral with the cam for rotating the cam, the profile of the claim having an arcuate cam edged section points of which along the arcuate edge section are at a gradually and smoothly continuously increasing distance from the shaft, and a circular cam edge section seamlessly continuously adjoining the arcuate edge section, points of the circular cam edge section along the circular edge being equidistant from the shaft, whereby the print head supported from the edge section of the cam is pressed against the platen roll at a constant pressure when the print head is supported from the circular edge section of the cam.

Abstract: An improved labelling system for automatically applying labels one at a time in sequence to a series of items, such as post cards, etc., is disclosed. Post cards or other articles are conveyed one at a time to a labelling position. Separately, a carrier web, releasably carrying adhesive labels, is also conveyed to the labelling position. The carrier web is sharply reversed about a narrow edge, enabling the label to be peeled off and applied to a post card or the like being conveyed automatically underneath. A plurality of pairs of elements, including drive rollers and pressure-applying devices cooperating therewith, are utilized to controllably advance the carrier web through the labelling unit. As a feature of novelty, the labelling unit is pivotally mounted in relation to the conveying means for the post cards or the like.
