DE328779C - Process for the finishing of endless metal belts, in which the belt is placed over two rotating disks, which drag it along through friction - Google Patents

Description

Metal belts for engines that should run at high speeds, must have exactly the same dimensions in all their parts. They also have to be precise just run. Both are made with belts, which are only produced by rolling, drawing or the like are not easily accessible. In many cases it is therefore post-processing required to run accurate and accurate

ίο to achieve the dimensions of the tape.

■ It is known to process closed metal strips in such a way that they can be over runs two revolving rollers, which they take along by friction, whereby the same-

t5 the machining is carried out in good time by rolling will. The present invention uses the arrangement of the belt running over two rollers under tension, replacing each but the rolling due to the machining

ao processing of the belt using tools (e.g. chisels, files, grindstones, Grinding wheel, spinning steel o. The like.) Which on the belt in the sense of its longitudinal axis Exert force, this force being through the

“5 friction of the belt on the disks over which it runs is overcome.

In the drawing, such a processing device is shown, ι and 2 are the two discs, which is the one to be machined

to tape 3 by rubbing it with you. The required Tension of the belt is provided by the weight 4 in conjunction with the movable Storage of the disc 2 causes. The processing of the revolving belt is history by the schematically indicated tools 6, 6. These tools can either be placed on a point of the tape, which is on the disc surface, or at a point between Allow the two disks to attack freely running lengths of tape. The latter happens useful in processing devices, which exact thickness "of all parts of the tape to produce by, for example, the tape through a guide roller 5 on the relevant Office supports and 'the tool at the support office on the ribbon attack.

An adjustable drawing die is expediently used as a machining tool, with the support of a leadership role or the like, of course, being omitted. This is created the possibility of the tape using any slow and gentle drawing process to subdue and carefully pull out the tape to the exact length.

Processing devices, on the other hand, which are used for post-processing the edges of the tape are determined, it is often more expedient to attack the circumference of the disc, because here the tape is insensitive to forces acting on lateral displacement.

Claims (2)

Patent Claims: i. Method for finishing endless metal strips, in which the strip placed over two circumferential discs which it entrain by friction, characterized in that the surface or the edges of the belt (3) with the help of tools (chisel, file, grinding wheel, spinning steel or the like) (6) be reworked, the forces exerted on the belt by the tools due to the friction of the belt the discs (1, 2) are overcome. 2. The method according to claim 1, characterized in that the tool (6) on a point of the tape length running between the two disks (1, 2) engages. 'For this ι sheet of drawings.
