(under subclass 60) Processes in which the work is chilled to a temperature below that of the normal working temperature of the surrounding atmosphere.
(1) Note. The removal of heat usually effects a change of phase of a constituent part of the lamina and/or adhesive, e.g., solidification of a material which is normally in the liquid state under ambient conditions.
(2) Note. Mere cooling of a previously heated workpiece to cause it to return to normal temperature is not included here, to be classified here the workpiece must be chilled to below normal temperatures.
