Title:
FLANGE CUTTING AND SEALING ULTRASONIC APPARATUS OF FABRIC
Document Type and Number:
Japanese Patent JPS60162844
Kind Code:
A
Abstract:
A improved anvil construction, for use in an ultrasonic apparatus for edge cutting and sealing moving lengths of at least partially thermoplastic material (M), particularly textile fabric having at least some thermoplastic fibers, and including a vibrating sonic horn (14) cooperating with and vibrating against an anvil (12) for such ultrasonic edge cutting and sealing as the material (M) moves between the sonic horn (14) and the anvil (12). The anvil (12) includes a peaked cutting edge (21) and first and second surfaces (22, 23) extending in respective opposite directions from the cutting edge (21) and is characterised by being adjustable to positions for effecting clean and sharp edge cutting and desired amounts of edge sealing in the material (M) while resisting wear on the anvil (12). Such adjustment is in the form of pivotal movement of an anvil member (20) to adjust the acuteness of the included angles (A, B) of the first and second surfaces (22, 23) extending from the cutting edge (21) of the anvil (12) and in the form of timed rotation of the anvil member (20) so that a fresh portion of the cutting edge (21) thereof may be positioned for contact by the sonic horn (14) when wear occurs on such cutting edge (21).
