Application October 1, 1952, Serial No. 312,549
12 Claims. (Cl. 270-61) My invention relates to a new and improved machine and method for cutting belt-loops from a roll of material and for applying these loops to a belt, in order to sew said belt-loops to the belt.
This belt may be the waist-portion of a garment.
One of the objects of the invention is to provide a machine which automatically feeds the loop-material at right angles to the feed of the belt-material, which automatically cuts off selected lengths of the loop-material, and automatically folds the edge-portions of the loopmaterial between the edge-portions of the layers of the belt-material.
Numerous other objects and advantages and features of my invention are disclosed in the annexed description and drawings.
Fig. 1 is a front or longitudinal elevation of the improved machine;
Figs. 2 and 3 are respective transverse sectional views on the lines 2-2 and 33 of Fig. 1;
Fig. 4 is a top plan view of the improved machine;
Fig. 5 is a transverse end view taken in the direction of the arrow marked 5A in Fig. 1;
Fig. 6 is a section on the line 6--6 of Fig. 4;
Fig. 7 is identical with Fig. 6, showing certain parts of the machine in different respective positions from their positions shown in Fig. 6;
Fig. 8 is a perspective view of a part of the improved machine; and
Fig. 9 is a cross-section which shows the finished article.
The belt-loop material M for forming the belt-loops is taken from a roll 1, which is turnably mounted on a shaft 2. The various parts of the machine are mounted upon the supporting base-plate P, which is fixed to a suitable table or other horizontal support 3.
The material M is initially led under and in contact with an idler roll 4, which is turnably mounted in the vertical and longitudinal legs 5 of respective angle plates 6. As shown in Fig. 4, the base-plate P is provided with longitudinal slots 7, in order to provide a longitudinally adjustable connection of the base-plate P to the table 3. After being longitudinally adjusted, plate P is fixed to table 3 by clamping members 8.
As shown in Fig. 1, identical and longitudinally-spaced guides G and Ga are provided for guiding the web of loop-material M. Each said guide is laterally adjustable, in order to guide webs M of diflerent widths. The guide Ga is shown in detail in Fig. 3.
The guide Ga includes a first laterally adjustable angleiron which has a vertical and longitudinal flange 9 and a horizontal and lateral flange or base 10. Said base 10 has a lateral slot 11. A block 12 is suitably fixed to the plate P. The vertical faces of block 12 abut the inner faces of the vertical flanges 5 of the angle irons 6. A clamping screw 14 adjustably fixes the base 10 to the block 12. The shankof this clamping screw 14 extends 2,821,385 Patented Jan. 28, 1958 iron of guide Ga has a vertical longitudinal flange 15 and a horizontal and lateral base or flange 16.
The base 10 is provided with an additional lateral slot 170. The base 16 is provided with adjustable clamping bolts 17, which have clamping nuts 18 in order to adjustably clamp base 16 to base 10. The lateral spacing be tween flanges 9 and 15 can be thus adjusted.
The base 10 is located in a lateral groove 33 of block 12, so that the top faces of base 10 and block 12 are flush. These top faces are very smooth, so that the web of material M can slip along said top faces with minimum friction.
A turnable feed-roll 19 is turnably connected by pivot 21 to the lower and laterally spaced ends 20a of a pair of inner rods 20 which are suitably fixed to each other.
The right position of feed-roll 19 in Fig. 1 shows the position of said feed-roll 19 at the beginning of its feed: ing stroke. The other position of said feed-roll 19, which is adjacent the left end of Fig. 1, shows the position of said feed-roll 19 at the end of its feeding stroke. As shown in Fig. 4, the inner rods 20 abut and are located between a pair of outer rods 26, which are clamped to the inner rods 20 by means of clamping members 27 and 27a. The longitudinally disposed rods 20 and 26 are turned in unison in a longitudinal vertical plane. They constitute a single longitudinal lever of adjustable length.
The shanks of the clamping members 27 and 27a extend through alined slots 28 of the outer rods 26, so that rods 20 and 26 may be adjusted in order to regulate their combined length. The top pivot member 22 of the rods 26 is also of the clamping type, in order to adjust the position of said pivot member 22 in the slot 29 of through said slot 11. A second laterally adjustable anglethe longitudinal arm or lever 23.
The arm 23 is pivoted at 24 to an upright 25 which is fixed to plate P.
One end of a tension spring 23a is connected to said upright 25. The other end of tension spring 23a is connected to the longitudinal arm or lever 23. This tension spring 23a yieldingly maintains the arm or lever 23 in the normal position which is designated as PR in Fig. 1. A stop may be provided to prevent spring 23a, which may be kept under selected tension, from turning arm 23 beyond its PR position. 7.
Fig. 8 shows a frame F, which consists of an angular bracket 73, which has legs 73a, 72 and 73b. Fig. 5 shows the head H of a conventional sewing machine, which has the conventional presser foot 71. The bracket-leg 73a is fixed to the sewing-machine head H by fastening members 75.
A transverse lever 30 is connected by a pivot 31 to the leg 73b. A hook 32 provides a pivoted connection between levers 23 and 30. When arm 23 is in its normal PR position, arm 30 is in its normal position of Fig. 5. When the free end of lever 30 is moved downwardly from said normal position by a downward pull on link 31, as by operating a conventional treadle, said lever 30 is turned clockwise from its normal position as viewed in Fig. 5, and arm 23 is turned counterclockwise, as viewed in Fig. 1, from its normal PR position to its actuated PP.position.
- Hence the feed-roll 19 is normally in the left position shown in Fig. 1, which is at the end of the feeding stroke of feed-roll 19. When the arm 30 is actuated by pulling the link 31a downwardly, the arm 23 is turned from its PR position to its PP position, thus moving feed-roll 19 in its non-feeding return stroke from left to right, as viewed in Fig. 1. When the operator releases link 31, the tension spring 23a turns arm 23 from its PP position to its PR position, thus moving feed-roll 19 longitudinally in its feeding stroke from right to left, as viewed in Fig. l.
As previously noted, an ordinary stop, which may be 3 adjustable, can be fixed to upright 25, in order to limit the clockwise turning movement of arm 23 under the force of tension spring 23a.
There may be enough friction on the feed-roll 19, so that said feed-roll will not turn during its feeding stroke, so that during said feeding stroke there will be little 01' no slip between feed-roll 19 and the material M. Also, the feed-roll 19 may be provided with a conventional pawl and ratchet device, so that feed-roll '19 is prevented from turning on its pivot 21 during the feeding stroke of feed-roll 19, and feed-roll 19 can turn freely on pivot 21 during the return stroke of feed-roll 19. Since one-way feed devices are well-known per se, this conventional detail is not shown in the drawings.
Fig. 6 shows the normal, unactuated position of a clamping rod 34, which is shown in the upper, nonclamping position in this figure. Fig. 7 shows said clamping rod 34 in lower clamping position. As shown in Fig. 8, the bottom transverse edge of clamping rod 34 extends across the entire width of the strip of material M.
Thisclamping rod 34 has a vertical cylindrical shank which isslidable in the vertical cylindrical bore of a nut 35, which is vertically and adjustably fixed to a hollow casing 36, an extension of which is fixed by fastening members 37 to the transverse arm or lever 30. Hence hollow casing 36 is moved vertically downwardly when a downward pull is exerted upon the link 31, while lever 23 is turned counterclockwise from its PR position to its PP position, and while feed-roll 19 is being moved in its non-feeding reverse stroke.
As also shown in Figs. 6 and 7, an upper cutter 43 is fixed by fastening members 42 to the casing 36, so that said upper cutter 43 is moved down in a cutting stroke during the reverse stroke of feed-roll 19. The clamping rod 34 clamps the material M firmly against the block 12, before the cutter 43touches the material M. The lower end of a compression spring 39 abuts a collar 40 which is fixed to the cylindrical shank of clamping rod 34. This collar 40 abuts the top of nut 35, when rod 34 is in its non-clampingposition of Fig. 6. The upper end of compressionspring 39 abuts the lower end of a nut 38, which is vertically adjustably fixed to casing 36.
The compression of spring 39- is adjusted by vertically adjusting nut 38 relative to casing 36.
The clamping position of rod 34- whichis shown in Fig. 7 corresponds to the actuated PP position of arm 23, and to the final cutting position of cutter 43.
As shown in Fig. 4, the casing 36 is fixed to arm 30, substantially midway between its pivot 31 and its actuating link 31a.
When the operator actuates arm 30, in order to turn arm 23 from its PR position to its PP position, thus moving feed-roll 19 in its non-feeding right-to-left return stroke, the casing 36 is lowered to quickly move rod 34 to its clamping position, and to quickly compress the spring 39' sufficiently to clamp the material, because the rod 34 has a short clamping stroke, which may be made as small as desired. The material M is thus clamped against reverse movement, very close to the beginning of the non-feeding reverse stroke of feed-roll 19 and the clamping pressure of spring 39 is maintained until the feed-roll 19 is almost at the end of its non-feeding reverse stroke.
Also, after rod 34 has temporarily fixed the material M against reverse movement, and substantially at the beginning of the reverse stroke of feed-roll 19, the upper cutter 43 is lowered sufficiently to co-act with lower cutter 41, which is fixed to block 12, in order to cut the material M between the shearing cutters 43 and 41.
The guide-chute 44 is fixedby rod 80 to bracket 73. Fig. 1 also shows the tip-edge Ma of the strip M, at the end of a respective feeding movement of feed-roll 19. Dnring each feeding stroke of feed-roll 19, the respective end-portion of the material M is pushed through said hollow chute-guide 44.
Fig. 9 shows the completed work, in which the belt consists of body layers 49 and 50, which have lateral inward folds 47 and 48 at their longitudinal edges, as further shown in Fig. 8. The material M which is used to make the belt-loop, has lateral inward folds or legs 46, which are located between the folds 47 and 48 of belt-layers 49 and 50, and the parts are assembled in the relation of Fig. 9 by two rows of stitches 70 or other suitable means.
When the folds 47 and 46 are formed as shown in Figs. 6-8, the belt-layer 49 and the loop-material M are supported on a plate 45, which is releasably held in fixed position. This plate 45 may be fixed to the frame of the sewing-machine.
The belt-layers 49 and 50 are led to the sewing mechanism through conventional folders Fa and Pb, which form the folds 47 and 48 in said belt-layers 49 and 50 in the well-known manner.
Fig. 8 shows the folding fingers 51 and 52, which are turnably connected by respective pivots 53 and 54 to respective vertically movable slides 55 and 56.
Respective torsion springs 68 urge said folding fingers 51 and 5-2 to turn inwardly, in order to form the folds 46 in the loop-material M.
Fig. 7 shows these folding fingers 51 and 52 in their final folding positions, to which they are actuated by the torsion springs 68.
The vertical slides 55 and 56 are vertically slidable on respective guides 57 and 58, which are fixed to the frame F of the machine and which are provided with vertical slots or recesses S.
A rod 59 is fixed to guide-blocks 60, which have extensions which are guided for vertical sliding movement in said slots S. The slides 55 and 56 are fixed to said rod 59 by clamping collars 61, which are adjustable on rod 59. A hollow casing 62 is also fixed to rod 59, which fits in alined bores of said casing 62.
A presser foot 63 is fixed to a rod 64, which is vertically slidable in the vertical casing 62. A compression spring 65 downwardly biases the rod 64, whose cylindrical shank fits slidably in a hollow nut which is adjustably fixed to the bottom of casing 62.
As shown in Fig. 4, said casing 62 has lugs 66, which are fixed to an angular arm 67, which is fixed by fastening member 67a to arm 30, so that the presser foot 63 'is lowered to clamping position when arm 30 is operated to actuate arm 23 to its PP position.
When the presser foot 63 is lowered to its clamping position, and spring 65 has been sufiiciently compressed, so that presser foot 63 clamps the median part of the severed belt-loop material against the body-layer 49 and against the fixed plate 45, the torsion springs 68 automatically turn the folding fingers 51 and 52 inwardly, to the positions shown in Fig. 7.
Fig. 5 shows a needle N. Two said needles N form the rows of stitches 70.
As above noted, when the presser foot 63 is in its clamping position of Fig. 7, the torsion springs 68 automatically turn the fingers 51 and 52 laterally toward each other, thus forming the folds 46 of the material M, between the folds 47 and 48 of the belt-layers 49 and 50, which have previously been formed by the folders F and Fa.
The slides 55 and 56 are lowered to their bottom positions of Fig. 7 and the fingers 51 and 52 are turned to their final positions of Fig. 7, while the feed-roll 19 is moved in its non-feeding return stroke, which is from left to right in Fig. l.
The guides 57 and 58 are adjustably connected to the lateral leg 72 of bracket 73.
As shown in Fig. 6, said leg 72 is provided with lateral and horizontal slots 74. The guides 57 and 58 are provided with clamping members 74a, which extend through 75 slots 74.
Spacer bars 76 are adjustably connected by adjustable collars 77 and 78 to the guides 57 and 58.
As shown in Fig. 2 and Fig. 5, the vertical flanges 90 and 87 of angular plates which have horizontal flanges 91 and 88, are respectively fixed to the guides 57 and 58 by fastening members 96 and 94.
Plates 86 and 85 are laterally adjustably fixed to the horizontal flanges 91 and 88 of said angular plates by clamping members 93 and 95, which extend through lateral slots 92 and 89 of the horizontal flanges 91 and 88. This provides additional adjusting means for different widths of the loop-material M.
The operation of the improved machine is as follows:
The lateral distance between the vertical flanges 9 and of the guides G and Ga is adjusted for the respective width of the respective web of loop-material M.
The lateral distance between the guides 57 and 58 is also laterally adjusted, in order to regulate the lateral distance between the slides 55 and 56 and their folding fingers 51 and 52.
The lateral distance between the plates 86 and 85 is also adjusted.
As previously noted, the plate 45 is releasably fixed. Hence a plate 45 can be selected, whose width is substantially equal to the folded width of the belt-layer 49. Said plate 45 may be of adjustable width.
The belt-layers 49 and 50 are respectively led over and below the folding plate 45, as shown in Fig. 8. The folds 47 and 48 are formed in the folders Fa and Pb. As shown in Fig. 5, the folder Fb is substantially horizontal and the folder Fa is downwardly inclined.
The operator then downwardly pulls the link 31a, thus turning arm 23 from its normal PR position to its actuated PP position, and the operator then releases the link 31a, so that spring 23a turns arm 23 from its PP position to its PR position, thus feeding the web of loop-forming material M in a stroke of selected length, which is selected by adjusting the position of pivot 22 in slot 29. While the web M is thus fed in a direction per-- pendicular to the belt-layers 49 and 50, in order to overlie belt-layer 49 in a crossing zone, said belt-layers 49 and 50 are kept stationary and the sewing-machine is kept idle.
The operator then exerts a downward pull upon link 31a, thus turning armor lever 23 from its PR position to its actuated PP position, and said arm 23 is temporarily kept in its actuated PP position. Substantially at the beginning of the turning movement of lever 23 from its normal PR position, the clamping members 34 and 13 are moved to their respective clamping positions, and cutter 43 is then operated to cut off the required length of the web M between clamping members 63 and 34, and the slides 55 and 56 are then lowered until their folding fingers 51 and 52 turn inwardly to the positions shown in Fig. 7.
The sewing-machine is then operated, while the arm 23 is maintained in its actuated PP position or close to said actuated PP position.
The sewing-machine has conventional feed mechanism, which is not shown, for feeding the layers of the work to the sewing stations at which the needles N operate.
The presser foot 71 of the sewing-machine operates in the usual manner to press the folds 47, 46 and 48 against each other at the sewing stations.
The presser foot 63 and the folding fingers 51 and 52 exert light pressure and a light frictional grip upon the layer 49 and its folds 47 and the folds 46, so that the feed ing mechanism of the sewing-machine can feed the work off the plate 45. Also, the operator can relax the pressure of the presser foot 63 and the folding fingers 51 and 52, by relaxing the pull on link 31a, during the sewing operation.
The slide 56 operates to pull the material out of the guide 44, after the cut has been made by cutter 43.
As shown in Fig. 8, presser foot 63 overlies only a part of the clamped loop-material M, so that the feed mechanism of the sewing-machine can grip the forward part of the belt-material M, and thus feed the severed piece of loop-forming material in the sewing direction.
The stitching station of needles N is close to the folding station which is provided by plate 45 and fingers 51 and 52, so that the two rows of stitches 70 are formed while the fingers 51 and 52 maintain the folds 46 and 47, until the respective stitches 70 are substantially completely formed.
For convenience, the belt-layer 49 is designated as the outer or top belt-layer, and the belt-layer 50 is designated as the inner or bottom belt-layer.
