PATENT OFFICE.

The object of the present invention is aimed at working with that by patents 85438, 90700 and 101961 protected printing machine for stockings from the application of the clamping frame and Eliminate inconveniences resulting from transport chains. The latter are the following:

First and foremost, a lot of clamping frames are necessary, which are expensive in and of themselves as a result of their construction, but then also in continuous operation, as experience has shown, as a result of the continuous removal and insertion into the machine, as well as the and slackening of the stockings suffer tremendously, namely are easily bent, and then no longer fit on the driving pins or blades attached to the chains, i.e. become unsuitable in a comparatively short time. Another essential disadvantage is that when clamping and unclamping the stockings on each frame each of the two closing lids J has to be opened and closed individually by hand, so that a lot of time is lost, which is made usable for the machine and its efficiency can be. Finally, there is one more major malady to be mentioned, which is particularly evident in brisk operations. The stockings are measured with a wooden stick before printing and sorted into piles according to their length in order to prevent the different lengths from being mixed up during printing. For the same purpose, the previous stocking clamping frames, whose adjustable tip holders are adjusted according to the individual stocking lengths to be printed, have been painted with different, conspicuously different colors red, white, blue, etc., which have been specially determined beforehand for each stocking length. In spite of this, as experience has shown, it has happened that individual stockings are accidentally thrown onto other piles that do not correspond to the length of the stockings in question and, in the haste and inattentiveness, have been stretched into the wrong frames, which naturally has the consequence that the stockings in question either Over the edge or too short printed, so are unusable.

By present invention. the clamping frames should now be completely eliminated. They have been replaced by iron plates AA ¹ (Fig. 3 and 5), which are screwed between the two transport chains B by means of the round pins P riveted to the two narrow sides of the same and in this way simultaneously stiffen the latter at the exact distance from one another. which is advantageous for the quiet operation and consequently also for the cleanliness of the pressure supplied.

On these plates A and A ¹ , the stocking S to be printed is placed against precisely adjustable stops G and by gripper J

Claims (2)

held, which latter sit on in the bearings L rotatable shafts W (Fig. 5) and by spiral springs K, each of which is fixed with one end in one of the bearings L and with its other end in the gripper /, always energetically down be pressed. On the shafts W of the grippers J levers H and H1 are attached, which, when the chains B are displaced by stops T and T1, which are screwed onto one of the two chain supports E on the machine and adjustable, move downwards into the position shown in FIG. 3 Drawn position are pressed and thereby open the gripper J for removing the printed stocking and inserting a new unprinted stocking. The stops T T1 are adjustable in such a way that the grippers J are opened and closed either simultaneously or one after the other. After the levers H and H1 have passed under the stops T and T1, they move upwards again as a result of the pressure of the spiral springs K and thereby automatically close the grippers / holding the stocking S. The levers H and H1 are so much offset from one another in the lateral direction (see in Fig. 4) and the rear stop T1 is correspondingly so much shorter than the front T that the front lever H laterally passes the rear stop T1, without being touched by it. This gives the possibility that both levers H and H1 can be depressed independently of one another by the stops T and T1 and still be moved downwards simultaneously or one after the other by adjusting the latter accordingly. There are now two such stops T and T1 both in front of and behind the pressure rollers, of which the stops in front of the pressure rollers allow the gripper J to open automatically for the purpose of inserting a new stocking to be printed and those located behind the pressure rollers automatically open the gripper J for removing the printed stocking. The levers H and H1 are kept long enough to give the operating workers the necessary time to insert and remove the stockings. - Since the tip holder in this construction cannot be adjusted according to the length of the stocking to be printed, because the stocking support plates A and A1 are cut firmly between the transport chain B according to the largest stocking length to be printed, another, much better device has been made to handle the printing on the one hand different stocking lengths to enable without adjustment of the tip holder and on the other hand, a mix-up of different stocking lengths during printing can be completely excluded. For this purpose, only one type of cardboard shape is used for all stocking lengths, which corresponds to the largest stocking length, and on the transport chain B, as indicated in FIG Corresponding to the individual stocking lengths occurring, attached to which the worker, because he always puts all stockings with the tip in the same place, immediately sees when inserting whether he has a stocking of the right or the wrong length on the cardboard form and in the In the latter case, you can take out the stocking in good time or, in the worst case, let the jig in question run empty through the machine without spoiling the stocking. In order to enable the timely start of the printing exactly at the double edge for the different stocking lengths, so much is no longer removed from the rear coating of the pattern rollers, as was the case with the machine according to patents 85438, 90700 and 101961, than the stockings to be printed are shorter, but since the pattern roller always has to print with the end of its covering up to the tip of the stocking, which is always in the same place in this construction, so much is removed from the initial covering of the pattern roller that the relevant printing length comes out , namely the division marks o, 1, 2, 3 and 4 on the chain simultaneously indicate the number of pieces of covering that must be removed from the pattern rollers, starting at the front. Patent-A ν proverbs: 1. A machine for double-sided printing of hosiery of the type protected by patents 90700 and 101961, characterized in that the removable hosiery clamping frames are replaced by pairs of plates (AA ¹ J ) firmly inserted between the transport chains (B) , on which the stockings are replaced by von Spring (K) -affected grippers (J) are held, which during the rotation of the chains for the purpose of inserting and removing the stockings for each pair of plates by laterally offset levers (HH ¹ ) and stops (TT ¹ ) on the frame independently can be opened and closed automatically by one another at the same time or one after the other. 2. A machine according to claim 1, characterized in that with a fixed tip holder the possibility of pressing ^{1 of} all stocking lengths occurring under ' Use of a size of the cardboard forms corresponding to the largest stocking length is made possible in such a way that the printing length of the individual stocking sizes is precisely regulated by removing or adding pieces of covering to the pattern roller and, furthermore, by means of partial lines corresponding to the different stocking lengths provided on the transport chain (B), a mix-up of different ones Stocking sizes are excluded during printing. For this purpose ι sheet of drawings.
