US Patent:

6533863, Mar 18, 2003

Filed:

May 17, 2001

Appl. No.:

09/859699

Inventors:

Jeffrey L. Robbins - Phoenixville PA

Assignee:

Bayer Corporation - Pittsburgh PA

International Classification:

B05C 1102

US Classification:

118500, 118 33, 118641, 118 67, 118 68, 118126, 118413, 156 72

Abstract:

The present invention relates to an improved doctor blade and bedplate apparatus wherein there is a recess in the bedplate from some position upstream of the doctor blade to some position downstream of the doctor blade. This recess or gap in the area of the bedplate under the doctor blade allows one to form an even or uniform coating on the back of a web of material. This is particularly helpful in forming uniform coatings on the back of a greige good which has face fibers of varying lengths. The present invention also relates to an improved process for preparing a relatively uniform coating on the back of a web of material.

US Classification:

156 72

Abstract:

Tufted carpeting can be manufactured employing polyurethane adhesives and cured face up without dripping, when one or more drip-reducing process steps of adding a non-Newtonian thickener to the adhesive or forming a viscosified or cured film on the outer surface of the adhesive are practiced prior to entry of the greige good into the curing oven.
