MACHINE FOR MAKING PADS FOR SOCK HOLDERS Flled Aug. 9. 1929 2 Sheets-Sheet 2 JGa/dSQL MM/f Patented Aug. 1, 1933 UNiTED STATES teaser MACHINE FOR MAKING PADS FOR SOCK HOLDERS Jacob Goldschmidt, Dusseldorf, Germany Application August 9, 1929, Serial No. 384,754, and in Germany Octoberl'l, 1927 1 Claim. (Cl. 22315) lVfy invention relates to a machine for finishing blanks into pads'for sock holders.
It is an object of my invention to facilitate the manufacture, and to improve the quality, of I such pads.
To this end, I so design my machine that the Preferably the edges are folded twice which improves the appearance and increases the life" of the finished article.
The pad is that part of a sock holder to which the leg bands and the strap are attached. Heretofore the edges of the pad were folded down by hand or by means of the 'templet aforesaid. Folding by hand is' tedious and inaccurate, and the drawbacks of the folding about a templet have already been set out. w .5 j The pads are made of suitable material, such as satin, with or without a lining of gauze, paper or the like.
The machine according to my invention is substantially a press having die heads, dies and "folders, and, if desired, means for heating any or all of the folders and die heads, for instance, by electric resistance heaters.
The means for operating the press will not be described as they are of the usual type, cams, I levers, etc., which will be obvious to any expert. In the accompanying drawings a machine according to my invention and the stages of its operation, are illustrated by way of example.
In the drawings Fig. 1 is a section of the machine on the axis of its die heads and dies,
Fig. 2 is a plan view of the upper die, with its folders,
Fig. 3 is a section'on the line 33 in Fig. 2, .5.;- Fig. 4 is a plan view of the lower die, with its folders,
Fig. 5 is a sectional elevation of the upper die head; Fig. 6 is a side elevation of the die head; Fig. 7 is a plan view of the upper die head, showing a plunger which is fitted to slide in the die head, Figs. 8 to 12 illustrate various stages of the manufacture of the pad. a Fig. 13 is a sectional plan view of the die head, the feed slide and the dies,
Fig. 14 is a section on the line XIV-XIV in Fig. 13, with the die head in its initial position, Fig. 15 is a similar section, with the die head in its final position with respect to the hole in the feed slide,
Fig. 16 is a section on the line XVIXVI in Fig. 13, showing the folding-down of the blank corners, and
Fig. 17 is a similar section, showing the first stage of the final folding operation.
The blank a, as punched, is shown in Fig. 8. The line along which the four edges or corners e and the edge strip are folded down, are shown dotted. bare incisions in the sides of the blank.
0, Figs 1 and 13 to 15, is a feed slide which is presented to the die head d. The feed slide 0 has shoulders q, q for supporting the edges or corners e, e, and a strip or ledge q for supporting the edge strip 1'. The relative size and shape of the die head (I and the hole 13 in the feed slide 0 will appear from Fig. 13. The blank 0. is placed on the feed slide 0 as shown in Fig. 14, with its corners bearing on the shoulders or and the edge strip 1 bearing on the ledge q. The die' head (1 is now lowered as shown in Fig. 15 and moves through the hole p, folding up triangular flaps of the blank at e, and a substantially rectangular flap at f, Fig. 9. The die head, with the blank in this condition, is'now lowered to the top of the upper die 12, Fig. 16. The upper die has folders i, as will be described in detail with reference to Fig. 2, and retaining springs g in the shape of the letter V inverted. The folders 2' advance and turn down the triangular flaps e and the rectangular flap ,f, as shown. The blank is now as shown in Fig. 10. The springs g are forced aside by the descending die head d and return when the die head ascends, holding the blank when the die re-ascends.
The folders 1' remain in their advanced position while the die head re-lowers and, moving through the hole inthe upper die 1) which corresponds to its contour, attains the lower die in together with the blank. While the blank moves The die head d is hollow and a plunger is is mounted to slide in it; When the blank is in the position Fig. 17 the die head (1 ascends While the plunger is is advanced by means which will be described. At the same time, a lower die head 0 is moved up into the hole of the. die to to meet thepl'unger k; Foldersn are new advanced by means to' be described which, being heated electrically, fold over and iron the. edges.v
of the blank. The lower die head 0 may also be heated electrically. The blank finished, Fig. 12, and is removedby the descend ing lower die head 0. r
The leg bands, not shown, are attached at the two side edges ee, and the strap; not shown;
is attached at the central edge I;
Referring now to Figs. 5 and 6, k is a plunger which is mounted to slide in the upper die head] at, u is a push rod at the upper end of tlre'"plung-' er-Ic, .9 is a yoke on the rod u, 7 are three rods extending upwardly from the plunger 7c through.
The folders are illustrated in Figs. 2 and 4, with the means for operating them. In the upper die 12, two fold'ers'are provided fior each corner at e, making four, and 'a fifth fo'ld'er' handles the flap at f; The foldersare guided between rollers on the face 'of'the die, and are supported by a ring h. Each 'folder i is slottedj at :r, the slots extending at an angle to'th'e is now" longitudinal axis of the folders, and a pin 11 is secured on the ring for engaging each of the slots 11:. A handle zserves for rotating the ring h to advance or retract the folders.
A similar arrangement, but with four folders n only, and an operating ring m, is provided for the l'o'wer diew, Fig. 4.
g are springs, of inverted V-sha'pe, which are secured on the upper die 1), Fig. 3, for retaining the blank when the upper die head has been retracted.
The folders n on the lower die may be heated electrically, and so may be the lower die head 0, in order to iron the pad during the last stage.
I claim:
In amachine for finishing blank into pads for sock holders; erecting dieshaving holes adapted to retain certain marginal portions of the blank, an upper die head adapted to move through said holes with the blank for erecting the retained marginal portions of the blank, means on the last erecting die'for' folding the erected portions down onto the body of the blank; a plunger on said upper die head, means for advancing said plunger beyond. the upper die head, a-finishing di'e having" a hole of larger area than said plunger, a lower die head adapted to enter the hole in the finishing. die in the opposite direction to the movement of said plunger, the blank being engaged between said plunger and 105 said lower die head; and'means'on said finishing die for folding over the erected portions of theblank" down onto the body of the blank inthe' clearance between said plunger and the hole in said finishing die.
