Welding mirror (1) or wear plate. The invention relates to a welding mirror for welding polyolefins, comprising a base material (4) which can be heated by heating elements; and a contact layer which is disposed on the base material (4) and is intended to come into contact with the polyolefins during melting thereof. The welding mirror according to the invention is characterised in that the contact layer (3) has a metal carrier matrix (5) having non-metallic particles (6) embedded therein. Moreover, the invention comprises a wear plate (7) for releasable connection to a welding mirror (1), wherein the wear plate (7) supports the contact layer.

Die Erfindung betrifft ein Verfahren zum Herstellen von Beuteln (30) aus Folie (44) oder dergleichen für Schüttgüter oder faseriges Material, vorzugsweise für Tabak (31), wobei eine fortlaufende Folienbahn (44) und/oder mindestens eine weitere fortlaufende Materialbahn (41) entlang wenigstens einer Schweißstation (45, 46, 47, 104) geführt werden, an der Abschnitte der Folie (33a) (und/oder des mindestens einen weiteren Materials (41) verschweißt werden, bevorzugt mit anderen Abschnitten der Folie (34a) und/oder mit dem weiteren Material (41), insbesondere mit Teilen eines mehrfach wirkenden Verschlussmittels (41). Bei diesem Verfahren werden die Folienbahn (44) und/oder die mindestens eine weitere Materialbahn (41) insbesondere taktweise wenigstens annähernd in Vertikalrichtung entlang der mindestens einen Schweißstation (45, 46, 47, 104) geführt und/oder die fortlaufende Folienbahn (44) und/oder die mindestens eine weitere Materialbahn (41), insbesondere taktweise, durch UltraschallSchweißen verschweißt.
摘要:
The present invention concerns a machine (10) for covering paper articles (1) with a sheet (2) of flexible thermoplastic material, comprising: ·cutting means (110), comprising a bar (110') provided with a heatable cutting tool (112) able to assume an operating position, in contact with the sheet (2), and a non-operating position, outside contact with the sheet (2); ·control means (120), able to determine the operating position of the cutting tool (112) for heat sealing and/or cutting the sheet (2). The machine (10) furthermore comprises means for controlling the temperature of the cutting tool, operatively connected with the control means (120) to determine the operating position when a pre-defined temperature threshold is reached by the cutting tool.
