Abstract
Official abstract text for this publication.
An ultrasonic sealing system in a machine for making composite webs in the production of absorbent sanitary articles includes a contact roller having an axis of rotation and including a central portion and a peripheral portion which is supported by the central portion and includes an outer surface forming the outer surface of the contact roller itself. The contact roller includes a sealing pattern on the outer surface of the peripheral portion and also includes springs acting between the central portion and the peripheral portion, which is supported by the peripheral portion by means of the springs.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ultrasonic sealing system in a machine for making composite webs in production of absorbent sanitary articles, comprising: a contact roller, said contact roller having an axis of rotation and comprising a central portion and a peripheral portion which is supported by said central portion, the peripheral portion including an outer surface forming an outer surface of said contact roller, said contact roller comprising a sealing pattern on said outer surface of said peripheral portion, said contact roller including a suspension system acting between said central portion and said peripheral portion, said peripheral portion being associated with said central portion by said suspension system. 2. The sealing system according to claim 1 , wherein said peripheral portion comprises a plurality of sectors each associated with said central portion by a corresponding portion of the suspension system. 3. The sealing system according to claim 2 , wherein the plurality of sectors are independent of one another. 4. The sealing system according to claim 1 , wherein said suspension system comprises a plurality of elastic elements. 5. The sealing system according to claim 4 , wherein said plurality of elastic elements each have a substantially radial line of action. 6. The sealing system according to claim 1 , and further comprising a suction system in communication with the outer surface of said peripheral portion for holding a composite web fed by said contact roller. 7. The sealing system according to claim 1 , wherein said peripheral portion is a hollow cylinder, a lateral surface of said hollow cylinder forming said outer surface of said peripheral portion, said central portion being inserted in said hollow cylinder. 8. The sealing system according to claim 1 , wherein said sealing pattern is raised on said outer surface of said peripheral portion.
