Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for dressing the polished surface of a separate cloth roll used for cloth polishing the surface of a stainless steel strip or the like.

Conventionally, the method of dressing the polished surface of a separate cloth roll is as follows:
It was done by lightly touching the grinding wheel etc. to the polished surface, but
Since the entire width of the roller-shaped polished surface in the lengthwise direction of the drum cannot be dressed at the same time, the finish of the entire polished surface becomes mushy and a uniform finish cannot be obtained.

In addition, the grinding wheel used gets clogged quickly, and the dressing process takes a long time.The present invention provides a separate dressing device for eliminating the above-mentioned drawbacks.

4-In other words, the present invention uses cloth abrasive paper that simultaneously contacts the entire width of the rotating cloth roll to dress the abrasive surface of the cloth roll, and a rolling blade of the cloth abrasive paper added from the roll of cloth. A backup roll for receiving the abrasive paper, an unwinding roll for supplying the abrasive cloth paper onto the backup roll, and a winding roll for winding up the used abrasive cloth paper from the backup roll. The object of the present invention is to provide a cloth roll dressing device for dressing the entire polished surface of a separate cloth roll.

The present invention will be explained in detail below based on the drawings.

The drawing is a perspective view of the device according to the invention.

1 is a separate cloth roll, and 1a is its polished surface.

Reference numeral 2 denotes a backup roll for receiving the reduction blade of the separate fabric roll.

3 is a band-shaped coated abrasive paper for dressing, and the surface of the coated paper is usually coated with coarse abrasive particles having a grain size of #36 to #8 and a suitable binder such as glue.1.・It is hardened with glue or a combination of these.

Reference numeral 4 denotes an unwinding roll for supplying the abrasive cloth 3 wound into a band onto the backup roll 2.

5 is a winding roll for winding up the abrasive cloth paper 3 used for dressing.

Although not shown, a tensioning device for the abrasive paper 3 is provided to prevent the abrasive paper 3 from wrinkling or sagging or moving from the backup roll 2 while the separate cloth roll 1 is being dressed. It is a provision.

When using this device according to the present invention, the abrasive cloth paper 3 is set onto the unwinding roll 4, and its leading end is guided from above the backup roll 2 to the winding device 5 and set under tension.

The width of the abrasive cloth paper 3 is preferably equal to or slightly wider than the body length of the separate cloth roll 1.

A separate cloth roll 1 is rotated and the entire width of the roll 1 is brought into pressure contact with the abrasive cloth paper 3 at the same time for dressing, thereby making it possible to obtain a uniform abrasive surface over the entire width.

After use, the abrasive paper 3 in the part where the abrasive grains have worn out or fallen off and can no longer be used, or the part which has become clogged and can no longer be used, moves the winding roll 5 to the length of the part where it can no longer be used. By rotating and winding up the abrasive paper 3, a new part of the abrasive cloth 3 is fed onto the backup roll 2, and by repeating the above operation, the dressing work can be continued efficiently, and its practical value is very great. There is something.
