DEFINITION

Classification: 425/383

(under the class definition) Apparatus comprising (1) means to deform, stretch, shrink or otherwise change or control the configuration or size of a preform, or (2) means to vulcanize a preform which means includes a preform support having the

same shape as the preform or capable of causing the preform to retain its shape.

(1) Note. The first means does not necessarily include a preform support of the same shape as the preform.

(2) Note. A shaped "charge" generally has not been considered a preform for this group.
