Definitions
- the invention relates to a cylindrical mandrel for a grinding or polishing sheet of a predetermined size, which is characterized by a particularly firm hold even with axial movement of the mandrel.
- the present invention is based on the object, even with axial stress on the grinding tool, with certainty. and to achieve a firm hold in the simplest possible way.
- a prism has a longitudinal bore with a corresponding diameter for receiving the sanding sheet and mandrel and has a slot arranged at an acute angle on one longitudinal edge, the depth of which corresponds to the clamping length of the sanding sheet to be folded,
- the mandrel according to the invention consists of a cylindrical body A with stepped part Ab and with a small hole Ac and longitudinal slot Ad at one end and an enlarged hole Aa with screw thread at the other end.
- the threaded pin Va of an extension V which has a central longitudinal bore Vb, also fits into the screw thread of the bore Aa having.
- the clamping mandrel B is greatly flattened at its front end and, in addition to a cutting-like front end Bd, has notches Ba on the narrow sides, between which prongs remain.
- the auxiliary device for this consists of a prism D with a longitudinal bore Da for receiving the mandrel A, including an E sanding sheet and a slot De arranged at an acute angle to the longitudinal edge, the depth of which corresponds to the clamping length of the sanding sheet ends Ea to be folded.
- the grain side Eb of the sanding sheet E is on the outside in order to ensure that after the introduction of the sanding sheet E in the position of the clamping mandrel B according to FIG. 8 and its twisting into the stellurg according to FIG.
