Description

The invention relates to devices for rolling a relief pattern onto a surface of a clay beam coming out of an instant press using a negatively rotating roller which is freely rotating in bearings.

Known devices of this kind in the course of operation cause a general deformation of the clay bar when the roller is pressed into the body of the bar.

In the described device, this disadvantage is eliminated by the fact that the roller is given a vibratory motion.

FIG. 1 schematically shows a device with a vibrator in the form of a motor with unbalances on the shaft; in fig. 2 is a view along arrow L in FIG. 1; in fig. 3 shows a variant of a belt driven device to the unbalance shaft of the vibrator; in fig. 4 is a view along arrow B in FIG. 3

A roller / with a negative pattern of a cylindrical surface rolling a relief pattern onto the surface 2 of the clay bar 3 coming out of the mouthpiece 4 of the belt press, as the bar moves in the direction of the arrow 5, rolls along the surface 2 of the bar 6 freely.

When rolling in a relief pattern, the roller 1 should be pressed into the body of the timber to the depth of the pattern relief. In order to reduce the total deformation of the beam with such an indentation of the roller, the latter is given a vibratory motion in the vertical direction. For this purpose, sub-frames 6, in which the axes of the roller rotate freely, are located in the supporting parts 7 of the platform 8, on which the vibrator is located, indicated by the numeral 9.

With the help of the rod 10 attached to the press frame 11 by means of a swivel 12, the platform 8 is kept in the working position. In one variant (Fig. 1 and 2) the vibrator consists of an electric motor

13 with unbalance 14 on the shaft. Alternatively (Figs. 3 and 4), the vibrator is made in the form of a shaft 15 with unbalances 16 rotating in bearings 17, mounted on a platform 18 freely supported on the axis 19 of the roller 20. The shaft 15 is rotated by means of a temporary gear 21, 22, 23.

When the vibrator is operating, the vibratory motion (in the vertical direction) is transmitted to the roller 20 (or /) through the supporting parts 7 of the platform.
