Abstract

In printers utilizing fanfold paper the edge of a new strip must be taped to the trailing edge of the strip being printed to ensure continuous operation. A device is described to tape the top side of the sheets without the use of vacuum. Device 10 consists of plate 11 to which is attached cutting and taping mechanism 12. Plate 10 contains location notch 13 on one edge and a series of pins 14 on the same edge. Plate 10 is of sufficient width to accommodate any anticipated width of paper. Mechanism 12 attached firmly to plate 11 with block 15 consists of mask arm 16 and cutter arm 17. Mask arm 16 swivels upward from plate 11 at point 18 in fixed block 15. To mask arm 16 is firmly attached mask arm 19 consisting of upright arms 20, 21 which serve as a guide for the adhesive tape.

Splicing Mechanism for Fanfold Paper

In printers utilizing fanfold paper the edge of a new strip must be taped to the trailing edge of the strip being printed to ensure continuous operation. A device is described to tape the top side of the sheets without the use of vacuum. Device 10 consists of plate 11 to which is attached cutting and taping mechanism 12. Plate 10 contains location notch 13 on one edge and a series of pins 14 on the same edge. Plate 10 is of sufficient width to accommodate any anticipated width of paper. Mechanism 12 attached firmly to plate 11 with block 15 consists of mask arm 16 and cutter arm 17. Mask arm 16 swivels upward from plate 11 at point 18 in fixed block 15. To mask arm 16 is firmly attached mask arm 19 consisting of upright arms 20, 21 which serve as a guide for the adhesive tape. Upright arms 20, 21 are aligned to center on notch 13. Cutter arm 17 swivels on mask arm 16 at point 22 in a direction perpendicular to arm 16. In operation, the trailing edge of the perforated paper being printed on is butted closely to the edge of the incoming sheet of paper along a line 23 on the plate indicated by notch 13 using pins 14 for alignment. Mechanism 12 is dropped down on plate 11 with cutter arm 17 swiveled in an upright position away from the plate. The end of the centrally perforated splicing tape (approximately 1/2 inch width) is placed about 1/2 inch from edge 24 of the paper and the tear perforation in the tape is aligned with the se...
