US Patent:

6457626, Oct 1, 2002

Filed:

Jan 29, 2001

Appl. No.:

09/772122

Inventors:

James F. Sheehan - Warren CT
Sylvio J. Mainolfi - Roxbury CT

Assignee:

Branson Ultrasonics Corporation - Danbury CT

International Classification:

B23K 106

US Classification:

228 11, 2281101, 156 731, 1565801

Abstract:

An ultrasonic rotary horn has tapered input sections for the conversion of axial acoustic energy into radial acoustic energy. The preferred rotary horn includes a first half having a first radial weld section and a first axial input section for receiving a first axial acoustic energy. The rotary horn further includes a second half coupled to the first half. The second half has a second radial weld section and a second axial input section for receiving a second axial acoustic energy. Each half has a coned section defined by an inner tapered surface and an outer tapered surface such that the halves convert a portion of the first and second axial acoustic energy into radial acoustic energy. Each inner tapered surface forms an inner angle with respect to an axis of the horn and each outer tapered surface forms an outer angle with respect to the axis.

International Classification:

B29C 6500

US Classification:

156 735

Abstract:

Carpeted panels comprising a thermoplastic substrate and a synthetic fiber carpet are produced by bonding the respective parts to one another using a vibration welding apparatus for causing the generation of frictional heat at the interface between the substrate and the carpet. One of the platen of the welding apparatus confronting the carpet is provided with a pattern of closely spaced pins engaging the carpet and urging the carpet into forced engagement with the substrate. On account of the closely spaced pins and the relatively low amplitude of the reciprocating motion, a bond is achieved substantially over the entire interface between the carpet and the substrate.

International Classification:

B31B 164

US Classification:

493209

Abstract:

The method of manufacturing a filtration bag for a liquid comprises placing two flexible thermoplastic sheets adapted to filter a liquid upon one another, and welding the sheets together along a desired seam line by vibration welding using tool means which forcibly engage the superposed sheets along the desired seam line.

International Classification:

B32B 3120

US Classification:

156 64

Abstract:

A closed-loop ultrasonic welding apparatus for sealing or welding thermoplastic material on a continuous basis wherein the material to be welded is fed through a weld station comprising a horn and anvil. The apparatus includes means for providing a first signal commensurate with a desired ultrasonic energy density in the material when welded, a second signal responsive to the feed speed of the material through the weld station, and a third signal commensurate with the power coupled by a power supply via a transducer and the horn to the material at the weld station. Control means receive the first, second and third signals and produce an error signal, which is responsive to the difference between the desired energy density and the actual energy density coupled to the material. After being subjected to further processing the error signal is converted to a control signal for controlling the output from said power supply and/or controlling the engagement force between the horn and material. Hence, the welding apparatus causes a predetermined energy density in the welded material irrespective of disturbances or changes in feed speed, engagement force between the horn and material, or the material itself.

Abstract:

Carpeted panels comprising a thermoplastic substrate and a synthetic fiber carpet are produced by bonding the respective pads to one another using a vibration welding apparatus for causing the generation of frictional heat at the interface between the substrate and the carpet. One of the platen of the welding apparatus confronting the carpet is provided with a pattern of closely spaced pins engaging the carpet and urging the carpet into forced engagement with the substrate. On account of the closely spaced pins and the relatively low amplitude of the reciprocating motion, a bond is achieved substantially over the entire interface between the carpet and the substrate.
