Abstract: 965,630. Printing apparatus; feeding webs. FRITZ BUSER, A.G. Jan. 10, 1963 [Jan. 11, 1962], No. 1220/63. Headings B6B and B6C. [Also in Division B8] A screen printing machine comprises a stationary table support 10, an endless conveyer belt or printing blanket 20 movable over the table support for transporting cloth 18 to be printed, and a support sheet 12 having a plurality of ribs 12a, thereon, Fig. 3, extending in a direction substantially parallel to the feed direction, and arranged to support one run of the printing blanket 20. The material of the support sheet 12 and ribs 12a is such that the coefficients of limiting static friction and sliding friction between the support sheet and the relatively movable surface coacting therewith are substantially equal. The support sheet may comprise fabric reinforced synthetic resinous material with ribs made of a polymide such as nylon attached to the sheet by gluing or welding. The ribs may also be formed from a shaped foil of synthetic material mounted on a textile or fabric backing sheet. Further, the ribs may be formed on the printing blanket 20 instead of the support sheet. During the intermittent operation of the printing blanket, the ribs 12a have the effect of guiding the blanket to prevent transverse deviations. Also, the ribs 12a prevent the displacement of air from between the support sheet and blanket during the wiping procedure of the printing operation, thus preventing a vacuum from forming. The conveyer belt or printing blanket 20 may be used for feeding web material other than in a screen-printing machine.

In the construction shown, the packages or bottles 18 are stored in two vertical magazines 14 which, together with two reserve magazines 15, are enclosed in a refrigerator compartment 12 of the cabinet, the bottles being transferred by hand from 15 to 14 as required. The delivery devices comprise rollers 45, each provided with a pocket 54 to accommodate a bottle, the two rollers being coupled together with their pockets 180 degrees apart by a chain 66 adapted to be driven by a motor 17. When a coin has been inserted in a coin slit 60 (not shown), the motor circuit is completed and the rollers 45 are rotated through 180 degrees, the motor circuit being then automatically broken by a mercury switch 91. As a result of this rotation (1) the bottle 18 lying in the pocket at the top of one of the rollers is deposited in the delivery shoot 44, and (2) the pocket on the other roller has been brought to the top and stop pins 57, 58 normally keeping the lowermost bottle in the magazine clear of the roller surface are automatically withdrawn so that this bottle falls into the pocket as it comes up to the top position ; the stop pins are reinserted below the bottle next above the one that has just passed into the pocket. When the magazines 14 are empty the motor circuit is prevented from closing by means of a mercury switch 101 mounted on a swinging arm 102 operated by a finger 106 in each magazine, the fingers being coupled together by a link 105 and being depressed by the bottles as long as there are bottles in the magazines. The switch may also cause an "Empty" notice to be displayed. The stop pins 57, 58 and the switch 91 are actuated by means of arms 51, 52, 53 fixed on the shafts 47 of the rollers 45. The arms 51, 52 are provided with cams 84 which, as the arms rise from their lower positions, engage and rock spring-loaded levers 81, 82 and withdraw the pins ; further rotation of the rollers releases the pins and they are reinserted by springs 86 on the levers. The motor switch 91 is fixed to a plate 92 pivoted at 93 and rockable through an angle determined by a pin 96 working in a slot 97. As the arm 53 rotates with one of the rollers 45, one of two pins 95 on the arm engages a cam face 94 on the plate 92 and rocks the latter and the switch 91 to break the motor circuit. The roller pockets may be lined with rubber 55.
