US Patent:

54725496, Dec 5, 1995

Filed:

Jul 8, 1994

Appl. No.:

8/273091

Inventors:

Eran J. P. Jurrius - Akron OH
Robert L. Karam - Akron OH

Assignee:

Enclosure Technologies, Inc. - Sharon Center OH

International Classification:

C09J 500

US Classification:

156311

Abstract:

A device for electronically seam fusing similar or dissimilar multiple polymeric materials by placing the materials between two opposing plates, wherein the plates have cooling tubes disposed within the plates and have the required combination of heating elements, non-stick heat barriers, and configuration enhancers disposed thereon. The opposing plates are then closed by a force which is regulated by a control feature which also governs the timing, length and temperature that is utilized by the heat elements and cooling tubes of the invention. Upon completion of the electronic seam fuse cycle, the multiple layers of polymeric materials will be fused together, and separated if desired, thus creating a seam that will be as strong or stronger than the individual material.

The opposing plates are then closed by a force which is regulated by a control feature which also governs the timing, length and temperature that is utilized by the heat elements and cooling tubes of the invention. Upon completion of the electronic seam fuse cycle, the multiple layers of polymeric materials are fused together, and separated if desired, thus creating a seam that is as strong or stronger than the individual material. The selection of seam fusing process parameters is determined by employing an optimization process that considers the impact each process parameter has in combination with one another. This ensures that desired output characteristics such as seam strength are obtained.

Abstract:

An apparatus and related method for manufacturing a full-fashioned glove from similar or dissimilar polymeric material includes a controller that actuates various components in the apparatus, a thumb mold that forms a thumb portion from two layers of a first material and a hand mold which forms a plurality of fingers and a cuff from the first material and a second material. Both the thumb mold and hand mold have appropriate cavities with apertures therethrough wherein a vacuum source, actuated by the controller, draws the appropriate material toward the surface of the mold prior to closure thereof. Upon closure of the molds, a fusing element is energized by the controller and the materials are fused to one another to form the appropriate portion of the full-fashioned glove. After the glove is removed from the remaining materials, it can be employed in various types of manufacturing industries. By employing a vacuum within the molds a full fashioned glove is manufactured which presents improved sensitivity in the finger areas and which enhances the productivity of persons using the full-fashioned glove.
