摘要： Apparatus for making profiled plastics tube and comprising two circulating endless chains, each making a plurality of mould halves (18) move along with the tube (2) coming from an extruder (1), these mould halves pairwise constituting a mould cavity in which the tube is being given its profile. According to the invention the moulds (18) are movable relative to the chain links (1, 2) in a direction perpendicular to the direction of movement (P) of the links. The machine frame is provided with guides (33, 35, 37) for the moulds, some located interiorly, others exteriorly, with respect to the chain loop, such that once closed, the cavity formed by the pairs of mould halves will remain closed and undisturbed up to the end.
Preferably the transitions (41, 42) between curved portions (36,43) and the operative portion (32) of the path (31) of the moulds at the entrance and the exit ends are bending points of mathematically calculated paths and the operative straight path tangentially joins said transitional portions.
In order to further eliminate vibrations and other disturbances in the regular course of the moulds it is preferable that the chains (46) are each provided with driving means (40) which are operative near the entrance end of the operative straight portion (32) of the path, and with braking means (44, 59-63) which are operative near the exit end thereof.

摘要： A method of making seals in tubular web provided with side gussets in which method, after making the seals, sensors for the inner gusset edges are withdrawn outwardly over a certain distance, to position of the sealing devices remaining unchanged, and after transport of the tubular the sensors are moved inwardly again and the new position of the inner gusset edges is observed. Subsequently, when a difference is observed as compared with the previous time, the position of the sealing devices is brought into correspondence with this observation before making the next seal.
A device for making seals in tubular web provided with side gussets, comprising guide members (14, 15) and gusset sealing devices (2, 3; 4, 5) which are movable independently of one another in lateral direction, and in that individual means (10- 13, 18-21) are provided to bring the position of the gusset sealing devices in correspondence with the position of the guide members in case the latter, after making a seal and displacing the material one or more unit bag lengths, observe a difference as compared with the previous time.

摘要： Method of and device for making perforations in the inner gusset portions of a tubular web of plastics foil which is provided with side gussets. Such perforations serve to remove air from the interior of bags to be manufactured from the tubular web. According to the invention the gussets are opened over a distance sufficient to introduce, in the interior thereof, a punching member, which is activated by exerting a pressure from outside the tubular web. A device adapted to perform this method comprises a separate carrier (5) provided at either one of its ends with rolls (10-13) and adapted to be introduced into the interior of the tubular web (1) where it is supported and maintained in its place lengthwise of the web, by two sets of rolls (16, 17; 18, 19) which are situated at the exterior of the tubular web. The carrier (5) is provided with perforating units (21-24) and the machine frame outside the tubular foil is provided with means (29-31) to exert through the web material, a force and to activate the perforating units. Preferably elements for opening the tubular foil (1) comprise sets of conical discs (42, 42a; 43, 43a; 44; 45) which are rotatable about spindles, such that one each in every set of rolls is situated in each of the two gusset halves.
