Abstract
A spring for a vibratory conveyor is described and which includes an elongated substantially planar main body which is mounted on a vibratory conveyor for moving a source of product, and which has a longitudinal axis, and a predetermined spring constant, and wherein the elongated main body can repeatedly flex and twist about the longitudinal axis without substantially degrading the spring constant of the elongated main body.
Claims18
A spring for a vibratory conveyor, comprising:
- an elongated substantially planar main body having opposite first and second ends and which are each mounted on a conveyor for moving a source of product along a given path of travel, and wherein the elongated main body has a longitudinal axis, and a predetermined spring constant, and wherein the elongated main body can repeatedly and resiliently flex, and twist about the longitudinal axis without substantially degrading the spring constant of the elongated main body.
A spring for a vibratory conveyor, comprising:
- an elongated main body having opposite first and second ends, and which further has a longitudinal axis, and wherein the elongated main body has a central core formed of a plurality of substantially longitudinally aligned, spaced, and pretensioned glass fibers which are cured, and encased within, an epoxy material, and wherein the central core has a top and bottom facing surface;
- a layer of adhesive deposited on the top and bottom facing surface of the central core of the elongated main body;
- and
- a top and bottom outwardly facing skin surface which are individually adhered to the top and bottom surface of the central core by the layer of adhesive which is respectively deposited thereon, and wherein the top and bottom outwardly facing skin surfaces are each formed of a woven fiberglass weft which is oriented about 45 degrees relative to the longitudinal axis of elongated main body, and which is further sandwiched between, and bonded to, overlying layers of a multiplicity of longitudinally aligned and pretensioned glass fibers which are cured, and encased within an epoxy material.
