Abstract
A processing machine including a movable support which can mount either one of a processing part and a workpiece and which can reciprocate between a first position and a second position, and a reciprocating part for reciprocating the movable support. A protective part is provided on the upstream side and/or downstream side of the movable support. The protective part includes at least one protective member with a synthetic resin sheet or a film that can be kept rolled in a free state when tensile force is not applied to the protection member and unrolled when tensile force is applied to the member. The protective member is rolled and unrolled by forward and backward movement of the movable support.

A processing machine comprising:
- a movable support means which can reciprocate between a first position and a second position, and which can mount one of a processing tool and a workpiece therein,
- a reciprocating means for reciprocating the movable support means, and
- a protective means, including at least one protective member formed of one of a synthetic sheet and a film which can be kept rolled in a free state when tensile force is not applied and unrolled when tensile force, is applied is provided on one of an upstream side and downstream side of the movable support means when seen from a forward moving direction from the first position to the second position of the movable support means,
- wherein the protective member is unrolled by the forward movement of the movable support means and rolled by the backward movement of the movable support means when the protective member is located on the upstream side of the movable support means, and the protective member is rolled by the forward movement of the movable support means and unrolled by the backward movement of the movable support means when the protective member is located on the downstream side of the movable support means.
