Abstract:
An anvil 200 includes a base 210 and projections 220 and 230. The base 210 is installed at an attachment position 112a on an outer peripheral surface 112 of a rotating drum 110. The projection 220 protrudes from a front surface 210a of the base 210 in a normal direction H of the rotating drum 110 and is formed in a line shape extending in the cross direction CD along the front surface 210a of the base 210. On the front surface 210a of the base 210, one end 220a in the cross direction CD of the projection 220 is provided forward of the other end 220b in a rotation direction R. In the projection 220, a cut portion 260 is formed to extend in a direction opposite to the protrusion direction of each protrusion 240. The cut portion 260 extends from the front surface of the projection 220, protruding from the front surface 210a of the base 210, to the vicinity of the middle of the projection 220.
Abstract:
A heat- seal device (12) generally includes a heat source (30), a thermal conductor (26), which encapsulates at least a portion of the heat source (30) and is capable of transferring heat from the heat source (30), and a thermal insulator (28), which substantially surrounds the thermal conductor (26) but leaves a portion (44) thereof exposed, the exposed portion (44) of the thermal conductor providing a heat- seal contact surface (46), which is adapted to be brought into contact with a material to be sealed.
Abstract:
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.

Abstract:
The problems associated with the prior art have been overcome by the present invention, which describes a tubular heating element which is resistant to damage caused by foreign material. The tubular heating element is pivotably attached to the side sealing machine at its leading (upstream) edge. The trailing (downstream) edge of the tubular heating element is moved by means of a compressible force, such as an air cylinder. In this way, the air in the cylinder pushes the tubular heating element downward into the plane of the film. However, a foreign object located on the film can overcome the force of the air cylinder, thereby lifting the tubular heating element out of the path of the film.
Abstract:
The invention relates to an apparatus for cutting a packaging material (4) for a package, comprising an ultrasonic welding device (2) that includes a sonotrode (3) and an anvil (5) for sealing the packaging material (4), the sonotrode (3) being rotatable about a first axis of rotation (X) and the anvil (5) being rotatable about a second axis of rotation (Y). The apparatus further comprises a cutting device (6) which includes at least one knife (7) for cutting the packaging material (4) and which is arranged within the anvil (5). The invention is characterized in that the knife (7) has a blade (8) with a cutting edge (28) that includes at least two tips (33, 35) and at least two curved sections (22) interconnecting the two tips (33, 35).

Abstract:
In einer Vorrichtung zum Ultraschall-Schweissen von Bauteilen (2a, 2b) werden Bauteile zwischen einer Sonotrode (3) und einem Gegenwerkzeug (4) eingelegt und mit UltraschallSchwingungen (U) beaufschlagt. Das Gegenwerkzeug (4) ist mit wenigstens einem Schwingungssensor (6; 16; 26a, 26b, 26c) versehen, mit welchem die von der Sonotrode (3) über die Bauteile (2a, 2b) auf das Gegenwerkzeug (4) übertragenen Schwingungen (S) messbar sind. Der Schwingungssensor (6, 26) kann insbesondere durch ein Piezo-Element gebildet sein, welches gleichzeitig zur Höhenverstellung des Gegenwerkzeugs (4) dient.
