Blocks of bags from thermoplastic tubular film - using rotary bottom jaw of welder and shear ensuring smooth workflow

A device for the prodn. of a stack of thermoplastic bags from a flattened tube of film fed continuously forward to weld and shear tools extending across the full width of the run, has, behind these tools, in the direction of motion, a punching sleeve, and behind this, a perforating tool reaching across the full width, working with corresp. pressure pads. Between the shear and the perforating tool, a second welding arrangement presses the goods against a support rail, and tacks each bag to the preceding one. A welding rail or a welding bolster for the transverse weld and shear arrangement, the punch sleeve and the perforating blade which form the lower jaw assembly are free to rotate with a support beam. These tools are duplicated at the same pitch and equally offset to the axis, at 100 degrees, so that each lower jaw can be brought into the working posn. relatively to the tools in the upper jaw. There is no disturbance of the sequence of bag making and bag block formation when the ejection ...

... 961,202. Making bags; seaming non- metallic sheet material. CELLOPLAST A.B. Nov. 3, 1960 [Nov. 4, 1959], No. 37882/60. Headings B5D and B5K. [Also in Division B8] Bags are formed by piling tubes of thermoplastic foil or pairs of foil sheets, alternate tubes or sheet pairs being of the same material and the intervening ones of a different material, so that when they are cut into lengths and sealed those adjacent one another adhere slightly to form a pack but do not fuse together. The two materials may be polyethylene and polyvinylchloride. The tubes may be sealed at intervals and then cut at each seal to form bags. Where foil sheets are used, their longitudinal edges are sealed first. The tubes may be wound on a drum, the roll of tubing cut radially, removed from the drum and opened out, the tubes being later cut and sealed by a hot wire or knife. Alternatively, the roll may be cut through and the exposed edges later sealed by a hot object either pressed on or held close to them. A hot gas ...

Bag block and process and apparatus for producing it

In a bag block (70), the rear wall (74) of its bag has only a narrow extension (76). In the region of the rear-wall extensions (76), the various bags are connected by means of passage welds (78) which predetermine edge recesses open towards the bag-block edge. These recesses are limited by an essentially solid wall of thermoplastic, on which the single-layer extensions (26) of the bag rear walls are formed linearly. This linear forming point constitutes at the same time a predetermined breaking point, at which the individual bags can be detached from the bag block by exerting a pull. The passage welds (78) project in the form of a conical ring above the surfaces of the bag block (70) and can thus serve at the same time for mounting a bag block in a sectional holding rail. ...
