and then a very oblique cut (Fig. 2), while on the rod itself the cut becomes straight and right-angled as a result of a hold-down Λ * to be attached in front of the knives.

In order to achieve an exactly straight, right-angled cut on both sides of the pieces to be cut, which is of the utmost importance for many jobs, but especially in screw production, it is necessary to hold the piece to be cut in the exact horizontal position while cutting and at the same time to bring it down horizontally with the descending knife. This is achieved in that the rod to be inserted no longer pushes against a stop, but rests on an up and down carriage A (Fig. 3), which also serves as a measure. The piece to be cut can no longer be printed diagonally by the knife, but is held by the carriage and horizontally guided with the knife downwards until the knife has cut through.

So far the process has probably already widely known, though little widely used: out because to be a great inconvenience loading \ stands, which makes the device so to speak, 'worthless. The piece to be cut off j namely vertically between the lower fixed \ stationary shear blades and the ■! The descending slide is clamped so tightly that it can no longer fall freely, but has to be removed by force. } This of course hinders the work in such a way that j an efficient cutting of large masses I is practically not possible. ;

The innovation in the present pre! direction consists in that the stop slide A is no longer guided vertically up and down I, but also goes back at the same time as it descends (Fig. 4). distance between the scissors knife and ^; Sledge is thus enlarged when cutting, while when opening the scissor knife. the stop slide returns to its original position. The success of this dojipel movement lies in the fact that the ibzubiieidc is never guided horizontally and thus receives a right-angled cut, but also becomes completely free between the knife and the stop slide after the cut and immediately falls by itself (Fig. 5). The work is not hindered in any way, you can cut continuously without any obstruction by jammed pieces.

In the case of the present device, the required double movement of going down and simultaneous going back has been achieved in the same way that the stop slide is not moved in guides running vertically downwards, but diagonally downwards. The more or less large deviation of the inclined guide from the vertical determines the distance by which the stop slide goes back. The lateral retraction of the stop slide can of course also be achieved in other ways than by inclined guidance. The pressure pin!) At the end of the cut holds the stop slide for a moment - until the scissors slide opens - in its lowest position, which gives the cut piece a little more time to fall freely. After the cut has been completed, the stop slide must go back up to its original position, which is achieved in the accompanying drawing by means of small compression springs, but can also be achieved in other ways, e.g. by counterweights (Fig. 6).

Ρλτεν τ-AjX proverb:

Device for cutting bar irons and the like to achieve a straight line right-angled cut on both sides of the sections, characterized in, that the stop which determines the length of the sections is designed as a movable slide that it when Going down at the same time is shifted sideways by the distance between the scissors knife and the stop slide.
