DEFINITION

Classification: 156/160

(under subclass 60) Processes which includes the step of applying an external force within the elastic limit of the material to at least one lamina prior to bonding to cause a change of form or dimension of the lamina and maintaining the lamina under such application of force during the bonding operation.

(1) Note. Merely holding a lamina taut during laminating operation is not considered an application of stress for this subclass.

(2) Note. Stretching of a fabric not to place the individual strands or filaments under stress but to cause the individual weft and waft strands or filaments to come closer to one another is not considered an application of stress for this subclass.

(3) Note. The external force may be one of tension or compression of the lamina. One form of tension is stretching.

229, for processes of stretching wherein the lamina is not under a stress or strain during the bonding operation. 494+, for laminating apparatus including means to apply tension or to stretch the work.
