Abstract: A protection suit for civilian or military use comprises a poncho-like part and a protective hood joined thereto. The poncho-like art of the protection suit consists of a flat sheet of thermoplastic material folded double and provided with an opening in the front sheet portion. The protective hood is prefabricated out of two flat sheet portions of thermorplastic joined together along a continuous weld seam and having openings. The opening in the back sheet portion of the protective hood is the same shape and size as the opening in the poncho-like part and the defining edges of two openings are welded together by means of a continuous seam. The protection suit can be manufactured entirely in a two-dimensional plane.

Abstract: Objects are packeted in bags (5) by means of a chain (1) of flat, flexible bags being conveyed, open at the top, through a filling station (12). Each bag in the chain has a rear main wall with a lip protruding from the opening, out past the edge of the front wall (51). In the station the lip is allowed to run along a support line which, seen in the general direction of feed of the chain of bags, diverges therefrom both horizontally and vertically so that the opening of the bag (5) can easily be opened by a jet of air without creasing the chain of bags.

Abstract: A conveyor for an article extends between two parallel rolls of stretch film (22, 22') to a turntable (40). The sheets of stretch film (24, 24') on the two rolls are joined together to form a curtain of stretch film. The article is brought into contact with the curtain and the sheets of film are joined together to form a sleeve out of the curtain around the article, thus securing the sheets to the article. The turntable is then rotated, thus winding the sheets several turns around the article. The sheets are then joined to form a new curtain of stretch film, after which the sheets are severed, releasing the wrapped article from this curtain.

Abstract: A process at continuous blowing of film such linear thermoplastic materials which after that the plastic melt has left an annular die, when introducing gas to the inner of the tube, forms a neck part having an essentially constant diameter and then forms a rapidly expanding main bubble whereby the speed of the film at the upper part of the neck is kept above 15 m/min.
