摘要： An installation for forming a tube of thermoplastic material with a socket having an external bead thereon, by pushing the tube end on a mandril consisting of two, spaced apart, axially movable mandril parts, and moving the two mandril parts towards each other while the outer surface of the tube is gripped by a mould having an internal recess corresponding to the bead to be formed on the tube. Compressed air, a compressible expandable rubber body, die or an inflatable rubber body is present in the space bounded by the two mandril parts and the inner surface of the tube. The length of the tube between the two mandril parts in their initial position is at least equal to the length of the bead to be formed.

摘要： A method for manufacturing a block bag of thermoplastic material with at least one filling valve from a tubular foil part having bottom flaps and at least one corner flap forming the valve being longer than the bottom flaps, wherein the bottom flaps are folded around a heat isolating piece and the stack of foils forming the bottom are heatsealed together by applying heat from both sides of the stack. The seals are obtained by spot welding, or formed as labyrinth seals. The end of the corner flap forming the valve may be stretched or subjected to a superficial incision, or creasing operation. By incision, or removing part of the corner flap forming the valve, a valve having a V form is obtained.

摘要： A plastic pipe consisting of an outer corrugated plastic pipe and an inner smooth wall consisting of a wear resistant elastomer, particularly a thermoplastic rubber fixed in the inner bottoms wave valley to said outer corrugated pipe. The inner wall consists of a pipe which has been coextruded with the outer corrugated pipe so that the inner and outer pipe are heat welded to each other.The cavities between the inner pipe and the corrugations may be filled with a foam plastic.This plastic pipe is used for repairing or renewing a sewage pipe by installing such a pipe from a vertical shaft of the sewage system into the sewage pipes. The interstices between the outer side of the corrugations and the inner side of the sewage pipe may be filled with a mortar.

摘要： A device for producing roll shaped packets of bags of plastic foil, whereby continuously a web is supplied in which the bags are held together through perforations, said device comprising two winding heads having lengthwise retractable and extendible winding fingers which can also be spreaded, the web during winding of one head running in between the fingers of the other head. Both winding heads are mounted at diametrically opposed locations of a revolvable disc having two fixed positions. The supply means comprise one roller within the line of circulations of the winding head situated at one side with respect to the vertical through the axis of the revolvable disc, and one roller outside the said line of circulation and situated at the opposite side of said vertical. A switch mechanism under control of a bag unit counter sets the non-operative head into rotation and brings the operative head to a standstill, whereby a perforation is caused to break and the winding is taken over by the head just started.
