Abstract: 1,169,790. Bundling machine. VITKOVICKE ZELEZARNY KLEMENTA GOTTWALDOV NARODNI PODNIK. 5 Oct., 1967 [10 Oct., 1966], No. 45395/67. Heading B8C. In binding a number of objects together by means of a steel tape and securing the tape by a double spot weld, tape 25 is withdrawn from supply reel 26 by rollers 4 and fed via guide 3 through the body portion 12 of a cutting mechanism and thence via guides 24 around the objects to be bound until the leading edge of the tape engages a support plate 2 fixed to the frame of the machine. Body portion 12 of the cutting device is then moved upwards by levers 15, 16 acted upon by hydraulic piston and cylinder 13 to clamp the tape against recess 19 in plate 2. Rollers 4 are then rotated in the reverse direction so as to tighten the tape 25 about the objects. Thereupon electrode 7 is operated to produce a spot weld between the overlapping parts of tape 25. The body portion 12 of the cutting device is then moved downward by the combined effort of pistons and cylinders 13 and 14 and the tape is cut by fixed knife 17. At this instant the whole tension in the tape 25 is taken by the spot weld, thus testing it. If the first spot weld withstands the tension the binding is completed by operating a second spot welding electrode 6.
