Definitions
- the invention relates to a process for the manufacture of endless metal bands which have been made endless by means of welded joints.
- Such a process which is known from the U.S.-A-3,922,771, makes it possible to produce endless bands which can be applied as part of a composite metal driving belt.
- the object of the present invention is to afford a process whereby endless bands can be manufactured from plate metal in a simple fashion and with a minimum waste of material.
- a strip of plate metal is wound and welded together edge to edge in a helical shape so as to form a pipe whose length is equal to at least a multiple of the width of the desired metal bands, whereupon ring-shaped parts are servered from the pipe to obtain said endless metal bands.
- the length of the band may be increased by rolling, which also has a beneficial effect on the welding joint.
- the welding is preferably done by a method in which no additional metal is supplied.

Abstract
Description
- The invention relates to a process for the manufacture of endless metal bands which have been made endless by means of welded joints. Such a process, which is known from the U.S.-A-3,922,771, makes it possible to produce endless bands which can be applied as part of a composite metal driving belt.
- One problem encountered with the process described in the said patent is how to obtain a welded joint of satisfactory quality. A very important aspect in this regard is the quality of the edge of the resultant endless band close to the weld, because it is there that an incipient fracture generally originates. This problem can be solved by removing the side edges from the band, for instance by means of a cutting operation, after the band has been made endless. Such a procedure is expensive and entails a considerable waste of material.
- The object of the present invention is to afford a process whereby endless bands can be manufactured from plate metal in a simple fashion and with a minimum waste of material.
- To this end, according to the invention a strip of plate metal is wound and welded together edge to edge in a helical shape so as to form a pipe whose length is equal to at least a multiple of the width of the desired metal bands, whereupon ring-shaped parts are servered from the pipe to obtain said endless metal bands. As a result, endless bands are obtained whose side edges have been machined after the welded joint has been made, which guarantees optimum edges of the endless band, especially near the welded joint.
- As such, it is a known technique to cut endless bands from tubular material, which affords the only possibility of obtaining endless bands that are not provided with a welded joint. It is, however, preferable by far to produce endless bands from plate metal because of their good properties such as constant thickness and level surface.
- By shaping a strip of plate metal into a helical form endless bands are obtained which are provided with an oblique weld, which enhances their strength.
- After the ring-shaped parts have been cut off, various machining operations can be carried out in order to modify their quality and/or size. Thus, the length of the band may be increased by rolling, which also has a beneficial effect on the welding joint.
- To elucidate the invention, an embodiment of the process will now be described with reference to the drawing.
- The drawing only gives a diagrammatic view of the way in which a strip of plate metal 1 is welded by a helical shape into a pipe 2. As a result, a helical
welded joint 3 is formed. By cutting off ring-shaped parts 4 from the pipe 2, endless bands are obtained with an oblique welded joint 5. - The welding is preferably done by a method in which no additional metal is supplied.
- It will be clear that the procedure described yields an endless welded band which can comply with all qualitative requirements, while keeping the amount of waste material down to a mimimum. This is of particular importance because the material generally used is of a very high quality and correspondingly expensive.
