Young Spring & Wire Corporation, Detroit, Mich., a corporation of Michigan Filed Dec. 28, 1956, Ser. No. 631,313 18 Claims. (Cl. 140-3) This invention relates to improvements in upholstery mat reinforcing machine. The invention embodies improvements in the machine for manufacturing reinforced fabrics disclosed and claimed in the patent to Leal, No. 2,218,758, issued October 22, 1940.

The principal objects of this invention are:

First, to provide a machine for weaving reinforcing wires into a web of loose fabric and severing the wires into sections and wrapping the ends of the sections around flexible reinforcing strands delivered longitudinally along the web to provide a finished web with transversely extending and transversely spaced sections of reinforcing wires connected at their ends to flexible reinforcing strands.

Second, to provide means for severing reinforcing wires woven into a web of loose fabric and wrapping the severed ends around longitudinal strands without damaging the web of fabric or interrupting the operation of the reinforcing wire weaving and web feeding means.

Third, to provide cutter means that will sever longitudinal reinforcing strands at selected positions along the length of a fabric web to which they are attached without damaging the web.

Fourth, to provide a machine having the aforementioned wire and strand connecting and cutting abilities in which the position at which the wires and strands may be connected and cut may be readily adjusted to produce upholstery mats having various arrangements and sizes of reinforced sections.

Fifth, to provide a machine of the type described which is accurate and rapid in operation and which maintains the loose fabric web in straight uniform condition relative to the reinforcing wires and strands that are applied thereto.

As indicated in the objects of the invention the present invention constitutes improvements on and additions to the mat weaving machine shown in the Leal Patent No. 2,218,758. Only so much of the prior Leal machine will be disclosed as is necessary to point out the function and coacting relationship of the present invention. Generally the mat weaving machine consists of a web feeding section 1 which supports a supply roll 2 of loose fabric such as woven burlap and delivers the fabric in a continuous web as at 3 to the reinforcing wire weaving machine. The wire weaving structure consists of a suitable framework 4 that supports a transverse cross bar 5 in spaced relationship above the table or way 6 (see FIG. 2) for the incoming web of fabric.

A lower former plate 7 is supported along the leading edge of the table 6 in opposed relation to an upper former plate 8 carried by the cross bar 5. The

former plates

7 and 8 have intermeshing toothed portions which form longitudinally extending fluted portions in the web 3. The reinforcing wires 9 are fed transversely of the web through the flutes by means of feed rolls 10 illustrated In order to guide the wires as they are fedin FIG. 1. transversely through the web, a guide plate 11 is vertically reciprocably mounted on the front of the cross bar 5 and provided with backing jaws 12 that descend into the depressions of the flutes to guide the wire across the web. The jaws 12 further function to back up the flexible reinforcing strands during the wire wrapping operation as will be described.

The plate 11 is vertically reciprocated by rocker arms 13 driven by cams on the transversely extending cam shaft 14. The cam shaft 14 and the wire feed rolls 10 are driven in timed relationship from a transmission assembly 15 as is a cycle control disc 16 and the cycle control chain 17. The cam shaft 14 rotates once for each wire feeding cycle and correspondingly actuates the guide plate 11 to receive a reinforcing wire. The feed rolls 10 may, however, be interrupted during preselected cycles of the machine as determined by the cycle cam 16 so that the reinforcing wire is not fed into the machine leaving blank spaces along the length of the web. The cycle cam drive and feed interrupting mechanism are the developments of others and so are not disclosed in great detail. Generally,

the crank wheel rotates once for each rotation of the,

cam shaft 14 and actuates the connecting rod 161 and ratchet lever 162 to advance the cycle cam 16 in a step byv step manner. The cycle cam 16 actuates a lever 163 for interrupting the feed action of the rolls 10 to prevent feeding of a wire 9 and form blank spaces in the web as determined by the shape and rotation of the cam 16.

Each rotation of the cam shaft 14 actuates a cam 18 and ratchet lever mechanism indicated generally at 19 to flexible reinforcing strands 24 onto intermediate portions of the web. (See FIG. 1.) The intermediate strands 24 are delivered into feed tubes 25 that are rotatably mounted in downwardly and forwardly inclined position in support heads 26 transversely adjustably mounted on the cross bar 5. The feed tubes 25 have forward ends 27 projected through selected jaws of the upper former plate 8 and are of such size at their forward ends so as to snugly but slidably support the reinforcing strands 24. The forward ends of the feed tubes 25 have bending lugs 28 projecting axially therefrom and these lugs are positioned at the bottoms of the tubes below the reinforcing wires 9 as the wires are fed transversely through the machine.

In order to sever the succeeding reinforcing wires between the pairs of rein-forcing strands 24 each support 7 head has a cutter bar 29 pivotally mounted thereon as at 30 and the cutter bar has a depending arm with a rearwardly notched cutter 31 on its lower end. The upper arm 32 of the cutter bar carries a follower roll 33 that is engaged by a cam 34 on the cam shaft 14. The cam 34 i carries a lift 35 that actuates the cutter bar to move the cutter 31 rearwardly into a slot 35 in the former plate 8 to sever the reinforcing wire 9.

' The rear ends of the feed tubes 25 are provided with meshing gears 37 retained on the rear side of the support head 26 by cover plates 38. A pinion 39 rotatably supported on the support head has a rearwardly projecting drive shaft 40 to which the actuating lever 41 is secured. The swinging end of the lever 41 carries a follower roll 42 received in an annular box cam groove 43 in the previously mentioned cam 34. The cam groove 43 thus transversely oscillates the lever 41 and angularly oscillates the gear 39 and through them the two feed tubes 25 so that the bending lugs 28 rotate in wrapping manner around the intermediate strands 24 as is shown by the dotted lines in 'FIG. 3. The cam lift 35 and the box cam groove 43 are angularly disposed on the cams 34 so that the cutter 31 first cuts the reinforcing wires and then the wrapping lugs 28 wrap the severed ends around the intermediate strands and return to the positions shown in FIG. 3. The earns 34 are angularly disposed on the cam shaft 14 to actuate the cutter and wrappers after each succeeding reinforcing wire has been delivered through the fluted web. 7

The conveyor 20 that carriesaway the reinforced web is similar in operation to the conveyor disclosed in the Richardson and Hood application but differs therefrom in that the links of the several conveyor chains 20 have a plurality of outwardly facing teeth 44 adapted to engage a wider. range of spacings of the reinforcing wires 9 on the web. By varying the length of each advancing step of the conveyor 20 it is thus possible to produce a web having a wide variety of reinforcing wire spacings.

The conveyor 20 advances the reinforced web with the reinforcing wires cut and wrapped in sections around the several

flexible strands

22 and 24 to a cutter mechanism supported on a second cross bar 45 positioned above and forwardly from the leading end of the conveyor 20 as appears in FIG. 8. The second cross bar 45 supports end cutter slides 46 and intermediate cutter slides 47 over the reinforcing

strands

22 and 24. The slides support rearwardly projecting guide rails .48 and 49. that project.

rearwardly along the conveyor 20 and are supported at their rear ends by angled braces 50. The rear ends of the

guides

48 and 49 have pointed ends 51 (see FIG. 10) that penetrate between the web of the fabric and the wrapped ends of the reinforcing wires 9 where the wires are connected to the reinforcing

strands

22 and 24. The reinforcing strands are thus advanced along the upper sides of the

guides

48 and 49 as shown in FIG. 9 in spaced relationship above the fabric to which they are attached. The cutter slides 46 and 47 carry vertically

reciprocable cutters

52 and 53 respectively that are slidable in lapped relation across the leading ends of the

guides

48 and 49 to sever the longitudinal reinforcing

strands

22 and 24. The

cutters

52 and 53 are actuated by arms 54 on a rock shaft 55 rotatably supported across the tops of the cutter slides 46 and 47. A cutter actuating means such as the air actuated cylinder 56 is connected to actuate the cutters. The cylinder 56 and the cutters are under the control of an electrically actuated valve 57 (see FIG. 1) and the valve 57 is conveniently controlled through the control cable '58 and a switch 59 positioned to be actuated by a cam 60 on the previously mentioned cycle control chain 17. The

cutters

52 and 53 can thus be actuated in a predetermined manner to sever the

longitudinal strands

22 and 24 at any preselected spacing along the length of the web as at a space where one of the transversely reinforcing wires is omitted. The web is then in condition to be severed into individual reinforcing mats. It is pointed out that the control cam 60 can be made either single or double to make a single cut in the longitudinal strands or to actually cut out a short section of the strands according to the wishes of the customer for the mats.

The finished mat as shown in FIGS. 11 and 12 consists of a section of the loose fabric 3 with a plurality of transversely extending reinforcing wires 9 woven therethrough. The wires 9 extend evenly and parallel to the edges of the mat and are divided into transverse sections wrapped securely around the reinforcing

strands

22 and 24 as at 61. The machine disclosed can be adjusted to provide mats of any length and of any longitudinal spacing of the reinforcing wires. The transverse spacing or position of longitudinal reinforcing

strands

22 and 24 can likewise be adjusted to any desired position. The mats are particularly desirable for covering'a spring structure preparatory to covering the spring structure with padding and upholstery. By dividing the mat into transverse sections a person seated on one section of the mat and spring structure will not deflect adjacent portions of the mat and spring.

Having thus described the invention, what is claimed as new'and'is desired to be secured by Letters Patent is:
