摘要:
Die Erfindung betrifft eine Schalenverschließmaschine (1) umfassend ein Siegelwerkzeugunterteil (6) mit einer Schalenaufnahme (8) und ein Siegelwerkzeugoberteil (7), wobei die Schalenaufnahme (8) eine Schneidnut (16), die jeweils umlaufend um jede Öffnung (9) für eine Schale (20) in der Schalenaufnahme (8) vorgesehen ist, aufweist. Die erfindungsgemäße Schalenverschließmaschine (1) zeichnet sich dadurch aus, dass die Schalenaufnahme (8) wenigstens eine jeweils in die Schneidnut (16) weisende Eingangsöffnung (17) und Ausgangsöffnung (19) zum Gasspülen der Schneidnut (16) aufweist.
摘要:
Palmate hygienic glove which is obtained in correspondence of the thermoplastic material layered tape, of the type consisting of at least one thermoplastic material film unwound from a reel and heat-sealed according to the shape of the fingers and the palm of the hand, and where said glove is heat-sealed in such a way as to follow the profile of the five fingers and the palm of a hand in such a way that in the area between each finger there is connecting thermoplastic material between said fingers and where at least one perforation line separates each glove from the following glove for the tear, where said perforation line has a semicircular development with angle between 90° and 180° sexagesimal degrees and with convex shape which originates at a first one of the two edges of said thermoplastic material tape and extends in a non-symmetrical way up to the second one of said two edges.

A heat-welding machine for welding a covering film on trays (100) provided with a perimeter edge (102) which is substantially flat, comprising: a horizontally-lying support frame (2) on which the perimeter edge (102) of a tray (100) rests, the tray (100) being arranged with a concavity thereof facing upwards; a dispensing reel (3) of a band (30) of covering film having a greater width than a width of the tray (100) situated in the support frame (2), an initial tract of an integral part of the band (30) being pulled onto the tray (100); a heated plate (4) for pressing the initial tract of the integral part of the covering film downwards onto the perimeter edge (102) of the tray (100) in order to weld the covering film thereon; means for cutting (40) for acting on the initial tract of the integral part of the band (30) of covering film, in order to separate a portion of the band (30) having a smaller width than the width of the band (30), and leaving a continuous waste (31) formed by two lateral strips (31') which remain attached to the band (30); and a take-up roller (5) of said lateral strips (31') which rotates and advances the initial tract of the integral part of the band (30) of covering film above the tray (100) located in the support frame (2).
摘要:
Zigzag-shaped pouches (20) are formed from flexible web material by positioning two portions of the web material in overlying relation and sealing them together along top (24), bottom (25), and opposite side edges (26, 27) of the pouch. The side edges of the pouch are made up of a plurality of linear segments connected end-to-end and alternately inclined in opposite directions to form a zigzag-shaped edge. Each linear segment of one edge is substantially parallel to a corresponding segment of the opposite edge, such that the two edges are substantially complementary in shape, whereby the pouch as a whole has a zigzag shape.
摘要:
The present invention relates to sealed pouches, and apparatus and processes for producing the same. The pouch (20) includes contoured first and second lateral edges (26, 27), with each lateral edge having concave and convex surfaces. The concave surface of the first lateral edge is substantially opposite the convex surface of the second lateral edge and the convex surface of the first lateral edge is substantially opposite the concave surface of the second lateral edge. Accordingly, a distance between the first and second lateral edges is substantially the same for all elevations of the pouch.
摘要:
Two types of gloves (10 and 30) with thermobonded seams that define fingers (22) and a thumb portion (12) that extends over palm (24) of gloves (10 and 30) thus allowing free thumb rotation. The method for manufacturing gloves (10 and 30) includes first forming thumb portion (12) by thermobonding one thermoplastic sheet (48) for glove (10) or thermobonding two thermoplastic sheets (74 and 76) for glove (30) into the shape of a thumb and second forming the remaining portion of gloves (10 and 30) by thermobonding thumb portion (12) to another thermoplastic sheet (46) for glove (10) or thermobonding thumb portion (12) to another thermoplastic sheet (78) for glove (30).
