Abstract
Abstract A coating roller and method of manufacture is disclosed wherein the roller is comprised of a magnetic cylinder and a plurality of magnetically attracted roller coverings individually supported on the outside surface of the roller. The edges of the coverings are separated to define distinct coating impressions on the product which is coated. Each covering of the roller is easily removed and replaced as required while keeping the remaining coverings substantially intact.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
A coating roller for applying distinct coating impressions to a surface comprising in combination a supporting cylinder including integral internally located permanent magnet means and having longitudinally and circumferentially extending positioning lines on the outer periphery thereof, and a plurality of magnetically attractable flexible roller covering segments positioned on said periphery in a single layer and held thereto by said magnet means, the edges of selected covering segments being separated and positioned on said periphery in accordance with selected positioning lines to define a desired pattern of said covering segments for creating a corresponding pattern of coating impressions on said surface, each of said covering segments capable of being individually removable from and replaceable on said periphery into modified patterns while allowing the remaining covering segments to remain in position thereon.
Claim 2
Dependent Claim
131 words
A coating roller for applying distinct coating impressions to a surface comprising in combination a supporting cylinder including integral internally located permanent magnet means and having longitudinally and circumferentially extending positioning lines on the outer periphery thereof, and a plurality of magnetically attractable flexible roller covering segments positioned on said periphery in a single layer and held thereto by said magnet means, the edges of selected covering segments being separated and positioned on said periphery in accordance with selected positioning lines to define a desired pattern of said covering segments for creating a corresponding pattern of coating impressions on said surface, each of said covering segments capable of being individually removable from and replaceable on said periphery into modified patterns while allowing the remaining covering segments to remain in position thereon.
Claim 3
Dependent Claim
37 words
A combination as set forth in claim 1 in which each of said segments has an outer coating-receiving layer, an intermediate load-carrying layer, and an inner layer comprised of a matrix having magnetically attracted particles embedded therein.
Claim 4
Dependent Claim
25 words
A combination as set forth in claim 1 in which each of said segments comprises an outer coating-receiving layer laminated against a flexible metal backing.
Claim 5
Dependent Claim
33 words
A combination as set forth in claim 1 in which each of said segments comprises an outer coating-receiving layer bonded against a backing layer, said coating-receiving layer having magnetic particles dispersed uniformly therein.
Claim 6
Dependent Claim
35 words
A combination as set forth in claim 4 in which said coating-receiving layer contains sufficient magnetic particles to create a firm magnetic attraction to said cylinder, without impairing the coating-receiving capability of its outer layer.
Claim 7
Dependent Claim
29 words
A combination as set forth in claim 1, in which at least one of said segments has a peripheral extension of reduced thickness to maintain separation between adjacent coverings.
Claim 8
Independent Claim
97 words
A method of making a coating cylinder having optimum versatility comprising the steps of providing a supporting cylinder having internally located permanent magnet means, placing longitudinally and circumferentially extending positioning lines on the outer periphery of said cylinder, providing covering segments having magnetically attractable means therein, placing said segments on said supporting cylinder in a single layer, and positioning selected segments on said periphery with separations between adjacent edges thereof in accordance with selected positioning lines whereby said magnetic means cooperate with said covering segments to maintain the position of said segments to form a desired pattern.
