"Punch needle for moving punch cards or the like"

. . · The punch card is used to store a number of information, -the are represented by perforations. Bin hole has a certain value according to its location on the map assigned. The assignment requires a certain division of the! Punch cards into columns.

The shape of the punch cards is rectangular with a preferred aspect ratio of about 2: 1. With consideration for the .Punch card readers, the holes are also rectangular limited. The narrow sides of the holes run parallel to the long side of the cards.

The punching of the holes is done either with a simple matrix line, column by column or by means of a Full die in blocks, in every possible hole a punch is assigned to the whole card. The punching punches or needles are always controlled ■ ".- via an electromagnetic mechanism.

Both the simple and the full matrix are fed step-by-step with the punched cards. However, this very ■ wise advance of the punch cards prevents a slight ^; further increase in punching speed. It is due to the fact that the punch needles during the sing riff

Punch card cannot perform a feed movement without to "damage" the sensitive card.

The innovation "now refers to a punch for Moving punch cards or the like, with the least possible effort with an exact punching process in compliance with the punch card standard a further increase in the punching speed and the pre-stroke speed can be achieved. she is characterized in that the punching die, which is moved to and fro, has a recess next to its frontal punching surface on the "stamp shaft in which the to be punched Material 'runs in and is returned to the punch also used for punching

The drive of the punching mechanism is mainly done by a crank mechanism. Either the punches or needles are compared to a fixed die or in a kinematic manner Reverse the die against the fixed punch system emotional. This difference is irrelevant for the innovation. Only the roughly sinusoidal course of the relative movement is essential, which has the same effect in both balls.

According to the innovation, the punch is of such a shape that it can be used in both. Forwards and backwards carries out a punching process, whereby the card runs into a recess on the needle shaft in a steady advance during the reversal of movement of the needle from forward to reverse. The ⁷ card is therefore not held in its feed movement by the inserted needle.

The figures "of the" drawing show the individual phases of a Stanzvdrgsnges with reciprocating stamp.

The punching surface 1 ^{1 of} the stamp 1 has the width of the standardized

part of the card part, but only about it hold a certain moment, the Tom card feed and the control pulse "is determined, the punch 1 punches in a known manner opposite a die 3 in the card 2 ! to oh j that according to the novel solution only approximately corresponds to half the size of the ÜTorm (Mg. 1 and 2).

During the reverse movement of the punch, which cannot happen in any short time due to the mass accelerations of the punch drive, the card 2 runs into a recess 4 on the stamp-SGhaft (S ¹ Ig * - 3).

In the return movement of the punch 1, in cooperation with the gate speed of the card, the second part (section) of the card hole 5 is punched to the prescribed length with the help of the punch surface 1 ″ of the recess 4 against the shear edges of the punch guide 8 (Hg. 4 ).

Shortly afterwards the punch 1 has reached its starting position again (S ¹ Ig. 5)

The height of the end face a (Pig. 5) should be as small as possible be because on the one hand it stamped the immersion depth of the punch determined by the card 2, on the other hand must not injure the accruing punch card by using it as possible happened quickly.

The end face a as well as the cross sections b and c are determined the quality of the stamp material used.

In the optimal design of the cross-section b this must

enlarge to the cross-section c Mn siöh. It. is in the sense of the innovation that the ^{punching surface 1 n} , which is inclined at the angle cL and acting in the return of the punch, already exerts a laterally shearing effect when the card 2 enters.

The slot card 2 should preferably be inserted be done in the direction of the long edge of the holes.

You are punching waste 6 of the return, for example suctioned or blown off a channel 7 in the punch guide.

According to the innovation, it is possible to arrange them in multiple ways the new type of punch both in columns with a simple die or in blocks with a so-called full die punch. What is essential is the uninterrupted passage of the punch cards possible as a result of the die shape mentioned or the like. Through the punching device.
