Filed:

May 20, 1986

Appl. No.:

6/865109

Inventors:

James O. Gallant - Dighton MA

Assignee:

SW Industries, Inc. - Providence RI

International Classification:

D06C 306

US Classification:

26104

Abstract:

Disclosed is a remotely-controlled adjustable-curvature roll of the present invention which includes a hollow, cylindrical axle in which two rods are inserted. Each of the rods is securely fastened to an endplate at one end of the axle, and the opposite end of each rod is threaded within one of two oppositely rotating intermeshed gears. An air-impact motor is connected to one of the meshed gears to rotate the gear to which it is connected. The rotation of the gears in one direction causes an increase in the compression applied to one of the rods while at the same time exerting an increased tension on the other rod which is connected to the oppositely rotating gear. This combination of tension and compression causes the curvature of the roll to change. A remote control unit regulates the flow of air from an air supply to the air-impact motor. The remote control unit includes a filter for filtering the air supply and an oil mist lubricator for adding a lubricant to the air supply.

Abstract:

The instant invention relates to a mechanism for aligning bobbins in, for example, a loom for subsequent movement of the bobbins to, for example, a stripping unit associated with the loom. The apparatus includes an inclined ramp upon which the bobbins fall and an upstream deflector mechanism to deflect and position a falling bobbin for engagement with the inclined ramp to align the bobbins and to prevent jamming thereof.
