The present invention comprises a Grinding or sanding machine for grinding or sanding a surface of a workpiece (8), wherein the grinding or sanding machine has at least one transportation device for transporting a workpiece (8) in a transportation direction; at least one revolving grinding or sanding belt (2); and at least one pressure beam (12) for exerting a pressure in the direction of the transportation device on the grinding or sanding belt (2),
wherein a plate (14) which is mounted so as to be movable in a plane that is perpendicular to the direction of the exertable pressure is disposed between the grinding or sanding belt (2) and the pressure beam (12).

A transport, driving or pressing belt, comprising at least one belt material having a lower and an upper face limited by two longitudinal edges and two transverse edges running obliquely with respect to the main extension direction of the belt, the belt material being closed and the longitudinal edges being folded down, and a method for manufacturing a transport, driving or pressing belt. To ensure high tensile strength over the complete belt length and avoid an edge tearing of the first belt material at the longitudinal edges, the transverse edges of a first belt material lie against each other in abutting relationship, and a second belt material is arranged centrically on the first belt material at least in the region of the transverse edges. The second belt material here nearly covers a width of 50% of the first belt material and is centrically glued with the first belt material.

An adaptable belt sander may comprise: a tool holder; a housing; a drive system comprising a first gear and a second gear configured to engage the first gear, the second gear coupled to a shaft; and a belt system comprising a belt extending from the shaft to a distal end of the adaptable belt sander, the adaptable belt sander configured to travel along a belt path in response to rotation of the shaft, the distal end having a rotating apparatus configured to engage the belt.

The invention relates to a press-on element 1 for an abrasive belt 30, in particular for wide belt grinding machines, consisting at least of a backing material 10 with a padding 3 and a sliding layer 4. To clearly improve the grinding results, a method and a press-on element 1 based thereon are employed which permits an additional cooling of the padding 3 and thereby the abrasive belt 30. The press-on element 1 here substantially consists of a padding 3 consisting of a spacer fabric. The spacer fabric is manufactured from two loosely woven textile surfaces which are connected to each other by pile threads so that the cooling medium can flow through the padding 3.
