Die Erfindung betrifft einen Papiersack (10) für Schüttgut wie Zement, Gips, Granulat, Tierfutter o. Ä., mit einem Boden (2) und mit einem dem Boden gegenüberliegenden Oberteil (3), wobei Boden und/oder Oberteil durch Zulegen der Seitenteile (5) um Seitenfalzlinien (4) gefaltet und verklebt sind, insbesondere in Form eines Kreuz- oder Blockbodens, wobei zur Verklebung der Seitenteile (5) wenigstens ein nach der Aufbringung aktivierbares Klebe- oder Haftmittel (11) vorgesehen ist, das zumindest von einer Seitenfalzlinie (4) bis mindestens zur gegenüberliegenden Seitenfalzlinie (4) der Seitenteile durgängig aufgetragen ist.
摘要:
A stripping device and method for removing a scrap portion from a cut-out section of a sheet of material. The stripping device can be used in combination with a corresponding jig assembly, and includes a first component being fixedly mountable onto a given jig of the jig assembly. The stripping device also includes a second component being slidably moveable with respect to the first component so as to be displaceable along a rectilinear path, the second component being operable between opposite draw-in and drawn-out positions, and being spring-loaded so as to be biased towards the drawn-out position. The stripping device also includes at least one stripping component being rotatably mountable about a distal end of the second component, and having at least one stripping surface being positioned, shaped and sized for stripping-off the scrap portion from the cut-out section of the sheet of material in combination with a stripping pin of the jig assembly as the stripping pin passes through the cut-out section of the sheet of material to be stripped off.

Liners for cooking vessels, cooking systems, and methods of making liners for cooking vessels are disclosed. The liner can be a multi-layer liner having a bag-like structure with a closed bottom having a bottom edge, a top opening having first and second top edges, and two sealed sides. The liner can have a first side seal extending along a first end from the top opening toward the bottom edge and a second side seal extending along a second end from the top opening toward the bottom edge. The liner material can include an aluminum foil sheet thermally laminated to a polymer film. The polymer film can include a biaxially-oriented polyethylene terephthalate layer coextruded with an amorphous polyethylene terephthalate sealant layer.

摘要:
A bag ( 1 0) in plastic shopper type with straps (1 1 0) having gusset structure re-folded at the centerline to form eight uniform layers, with bottom star welding, including externally of a multilayer tail (1 20) printable that also facilitates the production in coils (20) compact of large diameter and properly wrapped, ensuring uniformity of traction. A shaped die-cutting (1 41 ) longitudinally separates the straps from the said tail which remains joined to the bottom of the bag on the not die-cut portion (1 42), after the conventional separation from the roll, in the manner of protruding peninsula. The manufacturing process (31 ) of said bag ( 1 0), with production plant (30) by five stations (30A - 30E) provides the following production phases: Phase A) unwinding film from a reel, Phase B) cut with longitudinal welding and re-folding, Phase C) first welding-cutting, contextual (1 31, 1 41 ); Phase D) second welding-die-cutting, contextual (1 30, 1 40); Phase E) rolls winding.

Une machine de fabrication de sac à fond plat comporte un tambour (50) pour entraîner au moins une ébauche (6a) de forme tubulaire aplatie selon une direction d'avance, des premiers moyens de refoulage (51) en amont du tambour (50) pour marquer sur l'ébauche (6a) une première ligne de pliage (64) transversale par rapport à la direction d'avance, des moyens de pincement avant (52) sur le tambour (50) pour pincer un bord avant (68) de l'ébauche sur le tambour (50), dans une étape d'ouverture, et entraîner l'ébauche (6a), des premiers moyens de pincement latéraux (53) sur le tambour (50) pour pincer des bords latéraux de l'ébauche (6a)au niveau du première ligne de pliage (64). La machine comporte en outre des premiers moyens de réglage (7) pour régler en marche à la fois la distance entre le bord avant (68) et la première ligne de pliage (64) et la position angulaire relative des moyens de pincement avant (52) et des premiers moyens de pincement latéraux (53).
摘要:
The present invention relates to a method and assembly (6) for shaping a bag bottom (2). Such method comprises a step of providing a bag or envelope bag (1), which defines an inner compartment (4) suitable for containing at least one article, such as a food product, where such bag (1) is in a flattened configuration in which the inner compartment (4) is substantially collapsed, a step of providing a shaping assembly (6) which defines an outer perimeter (8) suitable for being least partially inserted in the bag (1), a step of engaging the outer perimeter (8) in the bag (1) and reciprocally moving the shaping assembly (6) and the bag (1). Lastly, the outer perimeter (8) is positioned at the bag bottom (2) so as to shape the latter and give the bag (1) an expanded configuration.
