DEFINITION

Classification: 83/287

(under subclass 286) Device provided with means to alter the dimension of the product in the direction of work movement.

(1) Note. For the purpose of this subclass, the length of a product is that dimension defined above regardless of the magnitude of that dimension relative to other dimensions; thus, as to this subclass, the length of a product may be smaller than the width thereof if short pieces are cut from relatively wide work.

(2) Note. Examples of the means defined above are means to effect (a) variation of the position of the work sensor relative to the cutter and (b) variation of the time elapsed between the sensing of work and the initiation of the tool action in response to said sensing.
