Abstract: A flexible web which is caused to run through a cross cutter to be severed at regular intervals in order to yield a series of discrete sections is engaged by a pair of holders which attract the web by suction immediately behind the severing plane when the cutter severs the web. The holders advance with the web and thereafter with the freshly formed section to prevent changes in orientation of the sections on their way to a removing station where they are expelled from the path of the web by block-shaped commodities which are draped into the respective sections. The surfaces of the holders are small and the length of each holder is a minute fraction of the length of a section, as considered in the longitudinal direction of the web. The holders are mounted on endless toothed belt or chain conveyors which advance the holders along an endless path having an elongated reach extending adjacent to the path of movement of the web and its sections toward, past and beyond the severing station.

Abstract: A method and system for preparing flat bottom thermoplastic sacks comprising process steps and means for forming a tube of thermoplastic film, collapsing said tube while forming two oppositely disposed gussets therein, simultaneously or spatially sequentially opening a gusset fold on each side of said collapsed tube to their full, lay-flat extent; simultaneously or spatially sequentially forming in each of the four gusset folds, a diagonal sealed seam over the portions of the tube width corresponding to the gussets along lines diagonal to the length of the tube so that the ends of the sealed seams of adjacent gusset folds are at least closely spaced or in contact so as to form an angle of at least approximately 90.degree.

Abstract: A parallelepipedic packing container of the type which is provided with a sealing fin which extends over the upper end wall of the packing container as well as over triangular, double-walled lugs adjoining this end wall. The sealing fin comprises a narrow sealing zone on the outer edge of the fin and a tearing perforation on the base line of the fin, the tearing perforation extending from the tip of one triangular lug to a point on the end wall of the packing container. The sealing fin is unsealed in the area between the narrow sealing zone and the tearing perforation, and moreover a corresponding sealing fin arranged at the base of the packing container is appreciably narrower than the sealing fin wherein the tearing perforation is arranged.

Abstract: An apparatus in which tablet strip packages are transferred with the aid of revolving suction devices out of a horizontally-functioning stamping device to a horizontally disposed conveyor belt. The suction devices are radially secured on a transfer head, which is rotatably supported on a swing. Thus, a straight-line transfer path from stamping device to conveyor belt is provided which allows for a shorter transfer time.

Abstract: Successive pouches severed from the leading end of a continuously moving strip of pouches are picked up by a series of spaced paddle assemblies and are turned from edgewise positions to broadwise positions. Each paddle assembly ducks into the pouch to pick up and turn the pouch and opens the pouch just prior to turning it to a broadwise position. Thereafter, the paddle assemblies release the pouches to carriers which advance the pouches through filling and closing stations. The carriers are more closely spaced than the paddle assemblies and are advanced at a slower rate than the paddle assemblies.

Abstract: A web 26 of packaging material on which a plurality of cigarette wrapper blanks 10 are defined in oppositely rotated and laterally displaced pairs, is fed between a reciprocatable punch 38 and a fixed support 36 having cooperating cutting edges 39 and counter edges 40, respectively, whereby the downward movement of the punch severs a pair of blanks from the web. The continued downward movement of the punch separates the two blanks of the severed pair through the cooperation of a further cutting edge 45 on the punch and a counter edge 46 on a turntable 41 disposed beneath the fixed support. The turntable is then rotated 180.degree. to successively feed the separated blanks to a suction conveyor 47.

Abstract: Apparatus for receiving a strip of flexible bags with capped spouts at longitudinally spaced intervals which are to be separated at transverse joints and then fed individually to a point of use. It includes draw rolls for drawing the strip horizontally into cooperation with a separator, means for vertically reciprocating the separator to pass through the strip and separate the leading bag therefrom, a guide channel for receiving the spout of each separated bag, and a feeding element for engaging the spout on each successive bag and arranging the spouts in predetermined spaced relationship relative to previously inserted spouts and with the leading bag in a selected position for its spout to be engaged by bag-withdrawing means.

Abstract: Continuous strip closed-bottom open-mouthed packaging bags are produced by continually making, at spaced intervals in a continuous flattened tubular oriented plastic film supply, a transversely extending heat seal to define a bag bottom, and, adjacent each heat seal, perforating the two plies of the film supply with a blade heated to effect annealing of the edges of the perforations and having a serrated cutting edge with spaced deep recesses to define connecting tabs between perforations.

Abstract: The present invention relates to a feeding mechanism for a bag manufacturing machine, in which a continuously fed film strip which has been folded double is cut to predetermined lengths to manufacture bags. The feeding mechanism includes a bar for forming film loops which is projectively provided on a number of transfer bodies which move in a circulation path, and is adapted to transfer the film in a looped state by the circulation of the transfer bodies and clamp the film before heat-sealing and cutting steps, thereby to precisely control film dimension.
