Description

Device for Hers @ tegizi n roof tiles The invention enables the production of the roof tile shown in Fig. i, its essentials Features are a sharp bulge or indentation at its head end the extrusion press, i.e. the cheapest and fastest way.

A pan brick that deviates from the straight line shape could previously only be produced using a revolver press. Here one had to pay expensive, use quickly wearing plaster molds, could only achieve low rebate heights, which no longer serve their purpose with a slight drying or firing delay and therefore require a precise sorting of the bricks, which continues to make them more expensive; in particular but if the known pressing device only allowed a slow one, the product in turn expensive production.

There are probably already devices ati strand brick cutting machines, which a slight deviation from the straight line shape by actuation a role or the like. The device according to the invention allows Deep and straight changes deviating from the strand shape on both sides of the strand at the same time.

This happens because the in its outermost width from the extruder exiting,-lying on the visible surface strand c over a ordinary, already known due to its design, provided with a waterable track Cutting machine, which performs a lifting movement for the purpose of cutting the nose will.

This lifting movement is used to actuate pressure bodies which make the indentation a or indentation b on the running strand during the duration of the cut.

Namely, the indentation a becomes a by a rotating upward movement correspondingly shaped pressure body (Fig. 2 and 3), which has the soft clay or Clay strand presses against the correspondingly shaped pressure body f.

The bulge h is caused by the fact that the over the entire length of the stone nest reaching pressure body g (Fig. 2 and 3) executes a downward movement and thereby holding the strand in place while the pressure body g1 moves sideways and thereby presses the surface h-h in Fig. i against the raceway d (Fig. 2). U m possible partial walking along with the movement indicated above To avoid bulge b, the pressure hull in Fig. 2 and 3 is brought up at the same time.

After completing the known cutting movement of the apparatus all aforementioned pressure hulls go back to their starting position and give this frees the strand to continue running.

The mass of the strand that becomes too much due to the pressure at k and L. is with cutting wires, which in the course of the running strand behind the cross-section point are attached, automatically cut off by the running activity.
