Abstract
Abstract A roller, such as a printing roller, is fabricated by sliding a cylindrical body having a longitudinally extending, substantially central opening over a rigid shaft designed to support the roller during rotation or the like. The roller is preferably cut to a desired length from a preformed, relatively long section of the material. A lubricating adhesive is used for the joint purpose of first lubricating the relative sliding movement between the cylindrical body and shaft during assembly and then adhering these parts together after assembly. In the preferred practice, a wet, polymerizable adhesive coats the opening of the cylindrical body, and a second different adhesive is used on the shaft. The lubricity of both adhesives contributes to the sliding of the roller relatively to the shaft, and subsequently the two adhesives form an adhesive bond between themselves and the parts to which they are applied.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A roller comprising a shaft, a precut, resinous elastic cylindrical body having a longitudinally extending opening mounted on the shaft, and dual adhesive means between the shaft and body contacting one another to form an adhesive bond therebetween, said dual adhesive means defining substantially concentric, tubular coatings, one adhesive means coating said shaft and the other adhesive means coating said longitudinally extending opening to bond the cylindrical body to said shaft, one of the adhesive means comprising a thermoplastic, hot melt material, and the other of the adhesive means comprising a thermoset reaction product of a polymerizable liquid, whereby both of said adhesive means prior to polymerization of said liquid adhesive means are adapted to exhibit a compatible lubricity in mounting said roller on said shaft by a lengthwise relative movement therebetween, and subsequently after polymerization of said liquid adhesive means to effect a bond between themselves and to said shaft and cylindrical body, respectively.
Claim 2
Dependent Claim
155 words
A roller comprising a shaft, a precut, resinous elastic cylindrical body having a longitudinally extending opening mounted on the shaft, and dual adhesive means between the shaft and body contacting one another to form an adhesive bond therebetween, said dual adhesive means defining substantially concentric, tubular coatings, one adhesive means coating said shaft and the other adhesive means coating said longitudinally extending opening to bond the cylindrical body to said shaft, one of the adhesive means comprising a thermoplastic, hot melt material, and the other of the adhesive means comprising a thermoset reaction product of a polymerizable liquid, whereby both of said adhesive means prior to polymerization of said liquid adhesive means are adapted to exhibit a compatible lubricity in mounting said roller on said shaft by a lengthwise relative movement therebetween, and subsequently after polymerization of said liquid adhesive means to effect a bond between themselves and to said shaft and cylindrical body, respectively.
Claim 3
Dependent Claim
14 words
The roller of claim 1 wherein said thermoplastic hot melt materiAl coats said shaft.
Claim 4
Dependent Claim
19 words
