Abstract: A saw guide for medicinal purposes is provided, having a handle and a sawblade guide element mounted on the handle to receive and guide a sawblade, said sawblade guide element including a frame mounted on the handle and a guide recess for the sawblade, mounted rotatably in the frame. The sawblade guide element can be secured on the material being sawed and can be adjusted in the position fixed at various end positions on the saw material. The frame is configured as a circle segment open on one side, into which the guide recess, which has an essentially circular base body, can be inserted in a form-locking connection. A stud is configured on the base body extending radially outward and having at least one essentially vertical slit for receiving the sawblade.

Abstract: The invention relates to a saw guide for medicinal purposes, with a handle and a sawblade guide element mounted on the handle to receive and guide a sawblade, and where the sawblade guide element consisting of a frame mounted on the handle and a guide recess for the sawblade, mounted rotatably in the frame can be secured on the material being sawed and can be adjusted in the position fixed at various notches on the saw material. To create a saw guide for medical purposes which is simple to handle and which ensures exact and precisely positioned guidance of the sawblade, the invention proposes that the frame is configured as a circle segment open on one side, into which the guide recess, which has an essentially circular base body, can be inserted in a form-locking connection and on the base body a stud is configured extending radially outward and at least one essentially vertical slit for receiving the sawblade is configured in the stud.

Abstract: A roller for a roller conveyor which has an integral base body (3) made of thermoplastic which is symmetric to an axis of rotation (9) and which contains a through passage (11) coaxial to the axis of rotation and is defined by two face sides (7, 8). The roller has a flanged pulley (4) integral to the base body (3) which is coaxial to the axis of rotation, a covering (34) arranged on the supporting section (5) which forms a running surface for work pieces or work piece supports, a tooth arrangement (45) constructed on the driving section (6) for at least one drive means active in a positive-locking manner, and bearings (17, 18, 29) arranged in the through passage (11) for rotatable support of the roller (1) on a shaft member (48).
