Abstract: An inert chemical material comprising primarily paraffin or wax is deposited on a surface of a plurality of sheets of glass and the sheets stacked with the deposited paraffin or wax forming intercalations therebetween. The paraffin or wax material may be deposited in granular or molten form. Advantageously molten material is deposited in spaced drops to form spaced raised spots over the surface of each sheet. Preferred dimensions, melting temperatures, compositions, etc. are given. A first group of spots may be initially deposited of paraffin or wax material having a lower solidification temperature, and thereafter drops having a higher solidification temperature deposited thereon. Apparatus for performing the methods includes one or more heated reservoirs positioned over a conveyor and having a group of nozzles spaced laterally of a sheet of glass on the conveyor and actuated to deposit molten paraffin or wax material drop by drop on the surface of the glass sheet.

Abstract: The invention relates to an apparatus for the assembly or permanent adhesion of sheets of glass with sheets of plastic material, comprising a pair of pressure rollers between which one passes the layers superimposed for assembly, which rollers being provided with, on a length corresponding at least with the size of the layers to be assembled, a hollow elastic covering which is filled with a fluid under pressure. In each roller the elastic covering is mounted to the roller (in a manner similar to a vehicle tire) by means of two rim-like elements, one of which is movable axially of the roller toward and from the other such rim. The elastic covering is like a tire but oversize in the axial direction. By adjusting one of the rims relative to the other, or the fluid pressure or both, the shape of the elastic tire-like member may be modified within wide limits to accommodate sheets of glass having complex, compound curves.

Abstract: A glazing including a sheet of glass and a sheet of plastic adhesively fastened thereto is manufactured by assembling into a stack the sheet of glass, the sheet of plastic, a thin flexible protective sheet, and a thick cushion sheet. The stack is enclosed in a bag of rubber or similar flexible material which is evacuated to degas the stack.. The bag with the stack therein is then subjected to heat and pressure in an autoclave to bond together the glass and plastic sheets, whereafter the protective and cushion sheets can be readily separated from the remainder of the stack.
