Abstract

1,110,355. Packaging gaskets; applying adhesive tape. ROLLS-ROYCE Ltd. 7 Sept., 1966, No. 40045/66. Headings B8C and B8F. [Also in Division B5] Adhesive tape 11 is applied to an edge of an inclined sheet 12, e.g. of cardboard when a carriage 15 carrying a roll of tape 18, traverses the length of the sheet. A clamp 36 holds the end of the tape and the sheet. The carriage which applies the tape from left to right (as seen in Fig. 2) to overlap the sheet edge is driven by a motor 31, operating a leadscrew 24 when a carriage microswitch (60), Fig. 3, is in contact with the sheet. When the board has been traversed microswitch 60 switches off the motor and a heating wire 45 carried on a sliding yoke 46 operated by a pivoted beam 52, is moved into contact with the tape which is thus cut from the roll. Movement of the wire is effected by a solenoid 55 energizing to pivot the beam 52. Switches 61, 62, limit carriage movement, and a sensing finger 63 prevents operation of the motor when insufficient tape remains on the roll. After taping, a gasket may be placed between the sheet and an untaped sheet and the tape bent over on to the further sheet by forcing through a slot (29), Fig. 1, in table (33). The remaining edges are similarly taped.
