3 Claims. (Cl. 140-105) This invention relates to a machine for cutting and forming a stock material and particularly, to apparatus capable of handling wire mesh and of forming kinks in the cross-wires thereof as the material is advanced along a support and ultimately wound on a take-up reel.

It is the most important object of the instant invention to provide apparatus of the aforementioned character that includes a plurality of forming Wheels cooperable with longitudinal slots in a supporting table to automatically kink the cross-wires of wire mesh as the latter is advanced along the table.

Another very important object of the instant invention is to provide in a kinking machine cooperating rollers for advancing the stock material and having intermeshing tongue and groove structure for receiving the cross-wires within the kinks thereof, thereby providing for positive advancement for the purposes aforementioned.

Other objects include the way in which one of the slots of the table receives a severing disc to bisect the advancing material as it is being kinked; the way in which the forming wheels are rendered adjustable by a special mounting permitting movement of the wheels into and out of the slots; the manner of driving the advancing rollers, as well as roller means to unroll the stock material from one end of the machine; the way in which the wheels are staggered so as to produce proper results; and the manner of adjustably mounting the cutter disc to accommodate for wear.

In the drawings:

Figure 1 is a side elevational view of a cutting and forming apparatus for rolled stock made pursuant to the instant invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is an enlarged, fragmentary, detailed, crosssectional view taken on line III-III of Fig. 2.

Fig. 4 is an enlarged, fragmentary, detailed, crosssectional view taken on line IVIV of Fig. 2.

Fig. 5 is a fragmentary, perspective view of a portion of the stock material after kinking and severance; and

Fig. 6 is a transverse, cross-sectional view through a pipe showing one application of the kinked material.

A suitable support broadly designated by the numeral 10 mounts an elongated, horizontal table 12, composed of a plurality of longitudinally extending plates 14 spaced apart to provide slots 16 extending the full length of the table 12. Suitable notched standards 18 are provided at one end of the support It) for rotatably receiving a roll 26 of stock material 22 to be kinked and severed through use of the apparatus forming the subject matter of the instant invention. 1

The wire mesh material 22 is of conventional character and includes a plurality of longitudinal wires 24 intersected by interconnecting cross-wires 26, the apparatus being capable of forming kinks 28 in certain of the crosswires 26 as best seen in Fig. 5.

The material 22 is unrolled and directed to the upper surface of table 12 by means of a pair of rollers 30 and 32 carried by the support 10, at least one of which (roller 32) is preferably driven through the medium of a continuous chain or the like 34. The material 22 extends between the rollers 30 and 32 as well as between a pair of rollers 36 and 38 at the opposite end of the support 10 which serve to advance the material 22 along the upper surface of table 12.

Roller 33 is also driven by the continuous chain 34 and the roller 36 is driven in the opposite direction by virtue of intermeshing gears 40 and 42 on rollers 36 and 355 respectively. A prime mover such as an electric motor 44, carried by the support 10 beneath the table 12 is operably coupled with the continuous chain 34 through a speed reducer 46 and an adjustable idler 48 is used to maintain the chain 34 in a taut condition.

A plurality of freely rotating forming wheels 50 are disposed for cooperation with the slots 16 to produce the kinks 23 in the cross-wires 26 automatically as the material 22 is advanced along the table 12. The wheels 50 are staggered in a suitable manner as is illustrated in Fig. 2 of the drawings, there being at least one wheel 50 for each slot 16 respectively.

In the arrangement chosen for illustration, two wheels 50 are provided for each slot 16 and they are mounted for rotation within yokes 52 that are in turn provided with upstanding, externally threaded stems 54. Stems 54 extend through bights 56 of U-shaped brackets 58 mounted on the support 10. Opposed nuts 60 on the stems 54 hold the wheels 5% in selected positions extending into their corresponding slots 16 as best seen in Fig. 3.

In order to provide for positive advancement of the material 22 along the table 12 without undue slippage, roller 36 is provided with annular ribs 62 and the roller 38 is provided with corresponding grooves 64 as shown best in Fig. 4 of the drawings. It is noted that the ribs 62 extend into the grooves 64 and that the same are disposed to receive the kinks 28 formed in the crosswires 26 by the plurality of forming wheels 50.

As the material 22 is thus advanced and kinked, it is bisected longitudinally by means of a cutter disc 66 extending upwardly through slot 68 in the table 12 so as to sever the cross-wires 26, preferably midway between the ends of the latter. Cutter disc 66 is driven by a prime mover 70 such as an electric motor, carried by the support 10 beneath the disc 66 and operably coupled with the latter by belt and pulley means broadly designated by the numeral 72.

In order to accommodate for wear in the disc 66 and thereby extend the useful life thereof, disc 66 is mounted for vertical reciprocation on a standard 74 forming a part of the support ill and spring-loaded idler means 76, swingably carried by the standard 74, maintains the belt of assembly 72 taut in all adjusted positions of the disc 66.

A take-up reel 78 rotatably carried by notched standards 86 mounted on the support 10, receives the kinked material 22 and may be rotated by use of a manual crank 82.

When the two rolls of kinked material 22 are removed from the take-up reel 78, they may be placed in use for various purposes and by way of example, Fig. 6 of the drawings illustrates the way in which a cementitious coating 84 on a pipe 86 may be reinforced thereby. Underground pipes 36 are conventionally protected with a coating 83 of asbestos or the like, and oftentimes the ciating 88 is in turn wrapped with a paper-like material 9 Some soil and terrain conditions require the additional placement of cementitious coating 84 and in accordance with the principles of the instant invention, the kinked material 22 is first wrapped over the coating 88 or the covering 9 if the latter is used. It is notable in Fig. 6

of the drawings, that when the kinked material 22 is spirally or otherwise wound on the pipe 86, the kinks 28 hold the same, particularly the longitudinal wires 24, spaced away from the covering 90 so as to properly receive and reinforce the cementitious coating 84. After such reinforcement is tied or otherwise secured in place, coating 84 may be placed thereon through use of conventional equipment that includes a gun nozzle 92 for spraying the material 84 on the pipe 86 until the kinked wire mesh is completely embedded therein.

Many other advantages will emanate from use of the cutting and forming machine above described and, therefore, it is desired to be limited only by the spirit of the invention as defined by the scope of the appended claims.

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