Embodiment Construction

[0022] figure 1 is a schematic side view of an apparatus 1 for sonication, wherein the apparatus is used in connection with the present invention. More specifically, according to the prior art, the device 1 comprises an ultrasonic device 2 with a sonotrode 3 implemented with a contact device 4 , namely an end piece.

[0023] pass figure 1 It will be appreciated that the ultrasonic device 2 is arranged in close proximity to a rotating abutment roller 5, the periphery of which roller 5 defines an abutment surface. The backup roll 5 is also suitably provided with a pattern for the ultrasonic treatment in question. The contact device 4 of the sonotrode 3 also faces the material and is arranged at a small distance from the outer circumference of the backup roll 5 . A small gap 6 is formed in this way, that is to say a relatively small distance is formed between the contact device 4 and the outer peripheral surface of the support roller 5 . A laminate consisting of two material ...

Abstract

The present invention relates to an arrangement (1 ) for processing of a material (7, 8) comprising at least one layer of material by means of an ultrasonic device (2) consisting of an ultrasound horn (3) arranged adjacent to an abutment (5; 5'), in conjunction with which a gap is defined between the aforementioned ultrasound horn (3) and the aforementioned abutment (5; 51), in conjunction with which the aforementioned ultrasonic device (2) is arranged for the purpose of feeding the aforementioned material (7, 8) through the aforementioned gap (6). In accordance with the invention, the arrangement (1 ) includes a pre-compression unit (9; 9') for the mechanical compression of the aforementioned material (7, 8) before it is fed through the aforementioned gap (6). The invention also relates to a method for processing of the aforementioned kind.

Description
