Abstract: A method and a machine for wrapping articles arranged in a group (3) in a tray (2) in stretch film (12). According to the method at least one strand of glue (38) is applied on opposite walls of the tray (2), whereupon a piece of stretch film (12) is extended over the group of articles (3) and the tray with the articles thereon is assembled with the stretch film in a manner ensuring that the film encloses the grouped articles. Two opposite end portions of the length of stretch film (12) are thereafter secured in position against the tray and gripping means (13, 14) release their grip on the outermost part of said film end portions. The latter are thereafter pressed against the strands of glue to attach the stretch film to the tray. The machine includes an elevating table (1) with manipulating members (13, 14) and glue-applicators (8) on either side of the elevating table. The manipulating members (13, 14) are arranged to move towards and away from one another. One manipulating member (13) is arranged to hold the stretch film (12) with the aid of clamping jaws and pull it over the grouped articles (3). The opposite manipulating member (14) is likewise equipped with clamping jaws (29, 31) serving to hold the stretch film (12) on the opposite side of the grouped articles (3) while the film is being stretched about the latter, and also with severing means (39) cutting off the required length of film. The elevating table (1) is arranged to raise the tray (2) with the group of articles (3) thereon against the stretch film (12) while at the same time the manipulating members (13, 14) are moved towards the tray and enclose the group of articles in stretch film, and with the aid of the clamping jaws (29, 33) press the film ends against the strands of glue (38) on the walls of the tray.

Abstract: A document sheet feeding and registration apparatus and method is described for deskewing and registering a document sheet (7) relative to a registered copying position on a copier platen (3) by feeding it against a sheet aligning document registration stop (18). Initially the document sheet is fed towards the registration stop (18) with a first document sheet feeder (17) exemplified by a widely transversely spaced pair of high friction sheet feeding rollers, which resist skewing of the document sheet. Then the first document sheet feeder (17) is removed from the document sheet (7) after its lead edge is engaged by a second document sheet feeder (16) and before the document sheet (7) engages the registration edge stop (18) so that final skewing control of the document sheet is only by the second document sheet feeder (16). The second document sheet feeder (16) is a single sheet feeding roller positioned centrally of the document sheet lead edge area and positioned closely adjacent the registration edge (18). This single roller provides a brief low rotational resistance deskewing of the document sheet (7) while driving the document sheet into final alignment with the registration stop (18). All of the sheet feeding rollers are positioned over the document on the platen extending through a backing plate (27) so as to be hidden during copying.

Title: A cheese mould

Granted: 1985-07-31
Abstract: An oblong cheese mould (1) having a substantially constant cross-section has in its side wall (3) slits (2) for drainage of whey from the cheese mass received by the cheese mould. According to the invention, the slits (2) extend transversely to the longitudinal direction of the mould, and their width, measured internally in the longitudinal direction of the cheese mould (1), is smaller than the cheese particles in the cheese mass, and the bottom (14) of the slits (2) facing the exterior of the mould is substantially closed, apart from channels (4) for drainage of the whey. This causes the cheese to be movable longitudinally of the mould because of its own weight so that the cheese obtains a very smooth surface, and thus the mould easily releases the cheese.
