Abstract: A hemming machine for simultaneously bending a flange on a first panel into engagement with an edge portion of a second panel to form a hem, and at least partially curing an adhesive located in the hem. The flange bending members and/or the top surface of the panel support nest of the present invention are heated using electric cartridge heaters, hot oil, or electric heating cables, for example. During the hemming operation the nested panels are in constant direct contact with the panel support nest, and the heated flange bending members are in direct contact with the hem for approximately 3 to 6 seconds (dwell time is dependent on whether the die blocks are heated or if the die blocks are heating in conjunction with the top surface of the panel support nest), which is generally sufficient to at least partially cure the adhesive located in the hem, thereby reducing the incidence of panel shift during subsequent transfer through the manufacturing process using conveyors, racks etc.

Abstract: A metal-working lubricant comprises an aqueous emulsion of (a) a long-chain aliphatic ester, amide, alcohol or acid, and (b) as a fugitive emulsifier an ammonium or volatile amine salt of a long-chain aliphatic acid.

The sheet can be formed or made into adhesively bonded structures of shaped components.

Abstract: A method of pretreating wood veneers with a wetting agent which reduces the amount of adhesive required to bond the veneers together in plywood manufacturing. The wetting agent can be water or a liquid solution containing an elastomer or plasticizer which leaves a thin film of solids on the veneer surface after it evaporates. The wetting agent is in part absorbed by the veneer to inhibit absorption of liquid from the adhesive. Also, the solid film left on the veneer flows on the glue line and wets the adhesive when the veneer is hot pressed. This promotes flow and spreading of the adhesive, even if it is partially dry, and thus results in more effective use of the adhesive so that the adhesive usage is reduced.

The invention is particularly directed to the preparation of a tire comprised of a polyurethane carcass applied to a cured rubber tread and to a tire comprised of a polyurethane tread applied to a cured rubber carcass.

Abstract: A protective material for use in articles of apparel such as golves, leggings, sleeves, aprons and the like. The protective material comprises a base layer composed of textile material, an intermediate layer composed of a cut-resistant material having intermeshing strands defining pores therebetween and an outer layer composed of solid, elastomeric material which retards penetration by liquid. The elastomeric material covers and is bonded to the base layer which prevents passage entirely therethrough by liquid, elastomeric material but permits partial penetration. The solid, elastomeric material extends through the pores of the intermediate layer and encapsulates the strands thereof. A method for producing the protective material comprises dipping an article composed of base layer and intermediate layer into a bath of liquid, elastomeric material preferably after absorbing into the base layer a coagulant for the liquid elastomeric material.

Abstract: In producing an article having a structurally primary part obtained by press-forming of a metal sheet to which a lubricant is applied beforehand and a secondary part stuck to the primary part with an adhesive, troublesome procedures for removal of the lubricant from the press-formed metal part precedent to adhesion-bonding of the secondary part can entirely be omitted without sacrificing the strength of adhesion between the primary and secondary parts by using an adhesive that has high chemical affinity with the lubricant remaining on the surface of the press-formed metal part. Preferably use is made of a solid lubricant containing organic polymeric substance as its principal component. In many cases the secondary part is made of a nonmetallic material, either an organic material or an inorganic material.
