Harold Flater, Ernst Teodor Waernhofl', and Nils Gunnar Franson, Norrkoping, Sweden, assignors to International Harvester Company, a corporation of New Jersey Application June 15, 1946, Serial No. 677,020 In Sweden June 25, 1945 I 7 Claims.

This invention relates to a twine-making machine and more particularly to an apparatus for making multiple strand twine. More specifically it relates to a machine for impregnating the individual surfaces of a plurality of twisted paper strands and in the same operation twisting said strands into multiple strand twine. v

A prime object of this invention is to provide an improved means for making multiple strand twine.

Another object is to provide'a machine for making paper twine, the individual strands of said twine being individually twisted and then impregnated with a water-resistant material thereby making said twine both flexible and durable.

A further object is to provide an improved machine for impregnatin individually twisted paper strands and subsequently twisting, said strands into multiple strand twine.

Another object is to provide an improved twine spinning machine, said machine having spinning disks and brake mechanism therefor, the brake mechanism being automatically operable'to stop the rotation of said disks upon the breaking of any of the twisted strands or twisted twine.

Other objects-will become more readily apparent from the embodiment of the invention which is illustrated in the following description and shown in the accompanying drawings, wherein:.

Figure 1 is a side .elevational view of a twinemaking machine.

Figure 2 is a sectional view taken along the line 2-2 of Figure 1.

Figure 3 is an elevational view of a portion of a braking means for a twine-making machine, said view being taken along the line 3--3 of Figure 1. Figure 4.is a sectional viewtaken along the line 44 of Figure 1, showing a cover member for a spinning disk.

Referring particularly to Figure 1, a twinemaking machine generally consists of a plurality of spinning disks ill for individually twisting paper strip into paper strands. The twisted strands are guided over a rotating impregnating disk generally indicated by the reference character II. From the impregnating disks the strands are carried to a twisting guide means l2 where they come together and are subsequently twisted into multiple strand twine by a twisting flyer i3. A braking or cutting-oil mechanism for the individual spinning disks I is generally indicated by the reference character l4. A drive mechanism i5 is operatively connected to the disks for v rotating the same.

Each of the spinning disks l0 consists of an annular receptacle l6.which is mounted for rotatlon on a spindle H, The spindle i'l' is'journaled in a bearing l8 mounted on a casing l8 which is carried on a support 20. The lowermost portion of the spindle I1 is keyed to a driven member 2| which operatively engages a driving member 22. The driving member 22 is resiliently held against the driven member 2i by means of a spring 23 and is keyed to a longitudinal drive shaft 24. A divisional application, Serial No. 790,644, was filed December 9, 1947, on the novel features of the spinning disks and the associated structure.

A coveror closure member 25 is positioned above the receptacle and is connected to a bracket 25'. The bracket 25' is pivoted at 26 to a support 21. A former 28 is centrally positioned on the cover member 25 and is journaled with respect thereto in a bearing 29 mounted in the bracket 25'. A twisting finger 30 is screwed to the former 28 for rotation therewith. A cap plate 3| is connected to the bracket 25' for fastening the former 28 and the bearing 29 to the cover 25.

The former 28 includes a vertical bore 32 in. axial alinement with a slot 33 of the twisting finger 30. The bore 32 is in communication with a cup-shaped socket 34 formed at the lowermost portion of the former 28.

A pair of radially extending arms 35 are rigidly connected to the former 28 and include radially extending resilient members 36, said members preferably consisting of a spring-like material. The resilient members 36 are adapted to engage the inner periphery 31 of the receptacle l6 when the cover 25 is in the closed position shown in Figure 2. The spindle I1 is provided at its uppermost end with a conical portion which extends into the receptacle [6 and partially projects into or mates with the cup-shaped portion 34 of the former '28, A support 39 is mounted on the bracket 25' and has Joumaled thereon a pulley or'guide wheel 40. 1

The impregnating means ll consists of a rotating disk 4! mounted for rotation about a vertical axis on a shaft 42. A drive means 43 is mounted for rotation about a transverse axis and is adapted to engage the clutch plate 44 thereby imparting rotating movement to the disk 4|.

The twisting flyer i3 is of conventional design and is supported at one end by a bracket 45. A bobbin or reel 48 is associated with the flyer l3 for collecting the twisted twine.

The braking or cut-off mechanism i4 is best shown in Figures 1 and 2 and consists of a brake shoe 46' adapted to engage the outerperiphery of the receptacle IS. A bell-crank 41 is mounted for pivotal movement on a support 48. The upper end of the bell-crank 41 is pivotally connected to a rod 49 which is slidably connected to the brake shoe 46'. A collar 50 having a slot 5! is formed integrally with the brake shoe 46 and is adapted to slide along the rod 49. A spring 52 is adapted to normally compress the brake shoe 46 against the external periphery of the receptacle [8. The amount of compression exerted by the spring 52 is adjustable by means of a threaded member 53. The lower portion of the bell-crank 41 is in operative connection with a cam 54 keyed to a longitudinal shaft 55.

Referring to Figures 1 and 3, it can be seen that the longitudinal shaft 55 is keyed to a crank arm 56. The crank arm 56 is in operative connection with a rotating stop 51 which is pivoted about a transversely extending shaft 58. The

stop 51 includes a contact element 58'. A drop sliding movement of the rod in one direction. A

spring 65 encircles one end of the rod 63, said spring being in abutment with one of the supports 64 and a contact member 61 formed at the end of the rod 63. A drop arm 68 is pivotally connected about a transverse axis as indicated at 89, said arm being provided with a loop 11 through which the twisted strands of twine may be guided.

It is, of course, readily apparent that the number of strands used in making the multiple strand twine can vary and is determined by the number of spinning disks used; the present form showing two such spinning disks. The braking means or cut-off mechanism which has been shown is typical for any number of spinning disks used.

Referring particularly to the operation of applicants machine, a plurality of spinning disks ID are driven by the longitudinal drive shaft 24. As shown in Figure 2, the paper strip is unraveled from the spool and by virtue of the conical portion 38 of the spindle I1 is guided into the cup-shaped socket 34 of the former 28. The paper is formed in the bore 32 and is thereupon twisted by the twisting finger into individual twisted strands A. Movement of the former and twisting finger is accomplished by the resilient members 35. As can be seen in Figure 2, these resilient members grip the internal periphery of the receptacle 16 when the cover 25 is in the closed position. Thus rotary movement 0! the receptacle I6 is imparted to the twisting finger and the former.

Each twisted strand is guided over a pulley 40 and over the impregnating disk 41. The impregnating disk is suitably driven about a vertical axis. A dry lubricant or other moisture resisting material such as wax is carried by the impregnating disk, and as the strands A pass over this disk, the peripheral surface of each strand is adequately and eiilciently impregnated. The strands A then are carried to the guide means 12 where they are brought together and subsequently 4 twisted into a finished multiple strand twine B by the flyer 13 as best indicated in Figure 1.

The spring 52 normally tends to lock the brake shoe 48 against the outer periphery of the receptacle. The brake shoe is held away from the spinning disks by means of the stop member 51 which locks the crank arm 56 and the longitudinal shaft 55 against counter-clockwise movement. It is desirable to immediately stop rotation of the spinning disks if at anytime the strands A or the twine B should become severed or broken. Provided the strand A is severed, the drop arm 68 will rotate and engage the member 61, pushing said member longitudinally to effect dropping movement of the weight 62. The weight 82 thereupon drops upon the contact element 58' of the stop 51. This causes the stop 51 to rotate thereupon releasing the crank arm 56 and the longitudinal shaft 55 for counter-clockwise movement. The spring 52 thereupon is free to force the brake shoe against the receptacle. Should the multiple strand twine B be broken the drop arm 60 will be free to rotate from its vertical and the contact element 60' will engage the contact element 58' of the release member, thus disengaging the stop member from the crank arm 58.

It can thus be seen that the objects of the invention have been fully achieved in the embodiment disclosed, and it must be understood that various modifications may be made which do not depart from the spirit of the invention as disclosed nor as defined in the appended claims.
