Description

Known devices for grinding surfaces butt end of a circular circle. In this invention, the working surface of the above EO circle is supplied with an edging paper passed through the cuts in the circle and during the operation of the circle, is sequentially moved by winding and winding on rollers, labeled inside the box, rotating together with the circle. The twisting of the aforementioned rollers is connected with the rotation of the circle by means of periodic reciprocal operations: 1 of the system of levers and gears.

In FIG. 1 depicts a common

view of the device, closed by a casing; FIG. 2- view of the device in the plan without a casing; FIG. 3- view of the device; FIG. 4 is a vertical section and a partially external view of a cube | su; and 5, -the detail of the inner box device.

The proposed device is available in. action from the engine W through the main wah., is closed by a fixed casing X, with which the coupling B is rigidly connected, which is freely seated on Balu A. Through

by means of the lever G and the spring shaft A is connected to three horizontal rails W, rigidly articulated along the con, with racks 3, to which the rivny Disc J2 is attached, receiving such

in the way, rotation from the shaft A. The disk I and the handle F pulled into it by the handle F in the grippers L attached to the disk by the clamp J, have coincident cuts /// N through which I slide the coil strip / formed: from the glued glued pane bands; paper. In the drawer are on both sides; vertical slots H in which. The ends of the axis of the rollers Y, which serve for winding the first winding of the first roll of paper, are laid. On one of the rails, from the side closest to the main shaft, i, there are sectoral slots that restrict the movement of the finger D of the lever D rotating in a horizontal plane around the axis C under the action of a protrusion, the muff-B on the finger D. Gori 3 octal Lever included: Enen with a vertical lever G, having a horizontal process touching the gear teeth C located in the SCW; plenpies with two gears T and T, axis; which, resting on the pillars 3, bring the I axes connected to them into rotation, rollers with paper rolls. To separate the disk H from the shaft and from the ij of the zhuha, use hole C in the casing for f pressing the lever jT when the diode mark coincides with the hole in the box. After placing a roll of paper in the box, and carrying it out through a slit S on the outer bottom surface of disc I covered with a soft Prokatka II and after starting the engine in motion, finger L periodically touches the protrusion C and thereby actuates gears T, T, which causes a gradual advancement of the paper on the lower surface of the disk, while rotating the disk with paper produces a grinding process with less of a strong pressure imparted to the device by pressing a hand. 1. A portable sanding / poop-up unit with sanding paper on the end face of a rotating disc, characterized in that

|} 1г1 шгУ. H., a disk, and. Associated with a rotatable shaft J, is provided with slots H for pulling along its outer end surface of a strip P of sanding paper passing through a box L inserted into the disc, equipped with, for rolling a strip, two shafts U, periodically rotated when the shaft A. rotates. 2. The form of execution described in paragraph 1 of the article, nka, characterized in that for automatic periodic rotation of the shaft U, the gears T, T coupled to the shanks C, turned lever under the action of spring-loaded lever C, rotated to the ground: (With the protrusion O acting on his finger D of the coupling O / 7, which is free to sit on the shaft A and is held fixed during the rotation of the latter.
