摘要:
Bei Folienverarbeitungsmaschinen mit horizontal bewegter Trenn- und Schweißeinrichtung (26, 27) werden die in unmittelbarem Anschluß an die Herstellung in vertikaler Erstrekkung gestapelten Beutel von einer zwischen der Stapelvorrichtung (42) und einem Förderband (66) bewegten Greifer erfaßt und auf das Förderband abgelegt. Eine bevorzugte Stapeleinrichtung besteht aus einem hin- und hergehenden Schläger (81), der den ersten Beutel auf die eine Ablage (42) und den nächsten Beutel auf die gegenüberliegende Ablage (42a) aufschlägt.

The invention relates to a perforator for performing perforations (5) on a moving paper (1) in its direction of movement. The perforator comprises a perforating tool (3), which has a perforating position, in which the paper is perforated, and a neutral position, in which the paper is not perforated, and a control apparatus, by means of which the perforating tool is optionally set either in perforating position or neutral position. The invention is usable for instance for perforating paper sheets printed out from a printer. The arrangement in accordance with the invention allows the same paper to be consistently used in the printer, while selectively producing perforation merely on the desired sheets.

Bei einem Verfahren zum Herstellen von Papier-säcken mit einer gestaffelten Verschlußklappe wird zunächst der Papierschlauch glatt abgeschnitten. Anschließend wird die Außenlage (1) entlang der längs verlaufenden äußeren Falzkanten (9) geschlitzt. Danach werden die Außenlage (1) und eventuell mit der Außenlage quer verklebte Innenlagen (2) quer zur Sacklängsrichtung zurückgebogen. Die nicht zuruckgebogenen Papierlagen (1a; 2a) werden anschließend zurückgeschnitten, und zwar vorzugsweise bis zum Ende des Schlitzes (7). Danach kann das Verkleben des so ausgebildeten gestaffelten Sack-endes erfolgen.

The invention relates to a method of forming cutouts (4) and transverse welding seams (10) in a sheet of film (5) that is advanced continuously at high velocity, wherein the cutouts (4) constitute areas that are delimited by cutting lines (6, 7), wherein the method comprises the following steps: a) the formation of the cutouts (4) in a sheet section with high sheet tension with cutting lines (7) that extend longitudinally of the sheet of film (5), and cutting lines (7) that extend transversally of the sheet of film, said cutting lines featuring a number of interruptions (8) that constitute support points whereby the cutouts (4) continue to be coherent with the sheet of film (5) at the support points, b) subsequent formation of the transverse welding seams (10) in a sheet section with low sheet tension.

The procedure consists of weaving on a loom two superimposed separate pieces of fabric, which are joined together transversally by weaving strands of warp at predetermined distances using strands of the weft, at the same time, in the direction of the warp independent bands with the corresponding hems in the longitudinal edges are formed in the loom, the sides of which are then subject to total or partial die cutting that conforms the bag or similar product. One of the fabrics to be used has, between the transversal and longitudinal hems, joining areas with floating strands of warp and joining areas with floating strands of weft, and this machine comprises means for moving, tensioning and aligning the fabric, and means for transversal and angular or curved cutting.
