Description

The invention concerns apparatus for applying divisions on measuring tapes provided with a supporting drum and a drum with sharply raised divisions and numerals with pointed edges, wherein the steel tape is coated on both sides with an acid-resistant layer. In the proposed apparatus, to communicate the roller with divisions and numbers of vibratory transverse movement for better cutting of the acid-resistant layer on the tape, the roller axis is provided at one end with a roller supported on a rapidly rotating disk with protrusions, and at the other end with a spring FOR pressing the roller to the disk.

In the schematic drawing of FIG. 1, a side view of the apparatus is shown; FIG. 2 is the same in front; FIG. 3-view of the feed rollers in front; FIG. 4-side view of the device.

The apparatus consists of a thrust roller 2 liters of roller /, equipped with sharp convex divisions and figures with pointed edges. Between the rollers I to 2, a steel tape covered on both sides with an acid-resistant layer is passed, thereby imparting a roller / vibratory transverse movement for better removal of the acid-resistant layer on the tape 8 of the roller 1 is provided at one end with an olik 7 supported on a disk rapidly moving from the motor 5 with protrusions b, I at the other end by a spring 9 for pressing the roller / to the disk 5. The feeding of the tapes is carried out with the help of the rollers 10, (FIG. 1-3), which clamp the tape on both sides. These rollers 10 are connected to the roller 2 by means of bevel gears //, 12 and 13.

For the manufacture of meters with double-sided divisions on the lower roller 2 (Fig. 1-2), the divisions and numbers are also engraved and a vibrating device is installed, as on the roller /. In order to cut tick marks and numbers in the manufacture of roulettes (Fig. A), the lower drum 14 is a support, inside which are located radially electromagnets / 5, which eliminate slipping of the tape when the drum 14 rotates. Electromagnets 15 automatically turn on when the drum rotates / 4 with this calculation so that only the top three electromagnets are adjacent to the part of the circumference of the drum 14 that is in contact with the tape. The feed can also be carried out by the rollers shown in fig. 3. The disks 14, 16, and 17 are interconnected toothed wheels. The discs 16 and 17 are driven in a transverse vibration motion, as is the roller / (Fig. 2). The cutting process is carried out in such a way that the disk / 6 applies ONLY dividing onto the tape. The disk 17 puts figures /, 2, 3, 4, 5, 6, 7, 8 to 9 in places of centimeters. The subject of the patent. 1. A graduation device on measuring tapes, in which there is a supporting drum and a drum, equipped with sharp convex divisions and numbers with pointed edges, and the steel tape is covered on both sides with an acid-resistant layer, characterized in that the roller axis 5 / from division Eg and numbers are provided at one end with a roller 7 supported on a rapidly rotating disk 5 with protrusions 6, and at the other end with a spring 9 for pressing the roller / to the disk 5 in order to impart to the roller 7 vibratory transverse movement for better penetration of the acid resistance th layer on the tape (Fig. 1, 2, 3). 2. The form of the apparatus, indicated in paragraph 1, characterized in that separate disk / b and / 7 and one support drum 14 (Fig. 4) are used to cut through the divisions of numbers or symbols.
