Sanding disc

A holding device, in particular a grinding disc, for a grinding member includes at least one support member that has at least one material opening configured for transverse transport of grinding dust to one side facing the grinding member in a plane parallel to a grinding surface. The holding device further includes at least one securing layer configured to secure the grinding member on the at least one support member. When decoupled from the grinding member, the at least one material opening is at least substantially open on a side facing the grinding member and on a side facing away from the grinding member is substantially delimited by the support member.

Holding device for a grinding means

A method for manufacturing a grinding tool which has a binding agent based on aromatic molecules includes cutting an abrasive material parent web with a laser device to form at least one inner contour of the grinding tool, and punching out an outer contour of the grinding tool from the abrasive material parent web.

Method and system for manufacturing a grinding tool

An exchangeable abrasive mechanism or disc for use on abrasive-mechanism carriers having suction holes includes a plurality of through openings that each have a centroid. The through openings are differentiated into three groups that differ in the radial disposition of the centroids. A first group comprises at least one, but not more than four, through openings of a first cross section. At least two of the through openings of the first group are disposed on a first circumcircle diameter that is substantially identical to one of the hole-circle diameters such that, when the abrasive mechanism is correctly disposed on an abrasive-mechanism carrier, they are in direct alignment with and can overlap, two corresponding suction holes. A second group of through openings of a second, preferably smaller, cross section, comprises at least four through openings that are disposed on a second circumcircle diameter that differs from the first circumcircle diameter.

A mounting element for holding a self-adhesive and/or flexible abrasive includes a supporting plate, and a distributing body. The supporting plate includes a plurality of suction openings which penetrate the supporting plate from a first side to a second side opposite the first side. A first side of the distributing body is in contact with the second side of the supporting plate, and a second side of the distributing body is configured to hold an abrasive. The distributing body includes a plurality of cavities which penetrate the distributing body from the first side of the distributing body to the second side of the distributing body, and which are mutually separated by a plurality of walls. At least one of the walls has at least one aperture which connects at least two adjacent cavities to each other.

Mounting with interconnected cavities for holding an abrasive, method for producing such a mounting, grinding system and use of such a mounting

A method for controlling a feeder of a gathering-stitching machine reduces the operating effort when setting the feeder, increases reliability when laying folded sheets on a transport device and improves quality during collating and stitching. Opening and closing times of grippers are regulated under program control, continuously and as a function of format when controlling the feeder of the gathering-stitching machine. Data relating to the dimensions and to the number of pages of the folded sheets is thus entered into a control device, from which data actuating signals for actuating elements of the grippers are generated.
