Abstract: A bag having an article applied to an inside surface thereof is formed in a continuous bag-making operation by conveying a bag-making film web and a continuous strip of material in joinable proximity with each other. The article is formed by severing the strip of material and at least one edge portion of the severed article is bonded to the continuous web of bag film. The longitudinal margins of the web are then brought together and bonded to form a tube with the article bonded to the inner surface of the tube, and bags are formed and severed from the tube with the article bonded to one inner surface of the bag.

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: In wrapping cylindrical goods or articles the article (1) is rotated about its axis, a stretch film (14) being wrapped round the article (1) substantially in a plane containing the axis of the article. A web-like wrapping material (24) is pressed against the cylindrical surface of the article (1) for rolling out on the article by rotation thereof. The stretch film (14) is wound over the material web (24). The stretch film can be one with a smooth and a sticky side, and which is pulled out from a supply (4). Winding the stretch film can be interrupted when the supply (4) is opposite one end surface of the article while the article rotation is continued a half turn, whereby the stretch film is laterally reversed in relation to the article. The film (14) can be initially wound with its smooth side in contact with the article (1) and later easily laterally reversed so that its smooth side is turned outwards to form the exterior of the article wrapping.

Abstract: In order to package a stack of goods in an envelope of heat-shrinkable plastic material such as polyethylene, with prevention of adhesion between the envelope and the goods which may themselves be wrapped in similar sheet material, the stack is placed on a pallet and is covered by the envelope whose lower rim is clamped between the legs of the pallet and an apertured supporting surface such as an upper run of a chain conveyor. The envelope is then inflated from below, by way of the supporting surface, with a low-temperature gas such as ambient air, to establish significant clearances between the stack and the inner surface of the envelope which is then thermally shrunk around the stack by training jets of hot gas onto its outer surface. In zones where the envelope is in contact with the stack, as along edges of the latter, the heating intensity may be reduced to avoid fusion with individual wrappings.
