METHOD AND DEVICE FOR WRAPPING HOSE.

Application filed June 19, 1925. Serial No. 38,281.

My invention relates to hose manufacture and it has particular relation to that phase of the art which pertains to the wrapping of the manufactured product.

The object of my invention is to provide a method of and means for wrapping hose.

In order to preserve a rubberized hose and protect it from any foreign materials during the time it is being transported from the producer to the consumer, it has been found advisable to wrap the coiled product in a manner not unlike that commonly employed in wrapping pneumatic tires. The wrapping machine employed for this purpose is an adaptation of that utllized 1n the tire industry. I have found, however, that unless the hose is carefully wound or coded and thereby given some rigidity or body, any loose strands or turns thereof Wlll 1nterfere sufficiently to make mechanlcal wrapping impossible.

According to my invention the hose 1s coiled on a suitable table or is first coiled and then positioned upon the table and tiedprior to its insertion in the wrapping machine. In this way, I have been able to obviate the former difiiculties.

In the drawings:

Fig. 1 is a perspective view of the device which I employ to effect the ob ect of my invention; and

Fig. 2 is a plan view, on a larger scale, of the supporting means and illustrates in outline a coil of hose built thereon in accordance with the principles of my invention.

The device includes a base plate 1 to which is. bolted a vertically disposed'journal memher 2. A shaft 3 is housed and maintained in vertical alignment by the journal. At the end of the shaft and rigidly mounted thereon is a disc 4 to which are bolted a plurality of vertically disposed standard members 5. Both ends of the standard members are provided with collars or flanges 6, which are integral therewith. The tops of the standards are fitted with spaced triangular blocks 7 which form the surface of the table.

In practicing the invention, one end of a coil of hose indicated by the numeral 9 is made into a loop and placed upon the block table surface. By rotating the stand, the remainder thereof is coiled about the loop to give a progressively larger flat spiral formation. After the coil has assumed the desired width, the balance of the hose may be superimposed to give a second or third layer if necessary. The ends are then coupled together and a cord or tape material 8 is passed around the transverseperiphery of the bundle in a helical manner, substantially as illustrated in Fig. 2. Inasmuch as the blocks are independent of each other, this step may be accomplished Without movmg the bundle or coil of hose 9. The ends of the cord are then tied and the bundle may be lnserted in the wrapping machine and covered in the usual manner. Although the hose and cord are shown in outline, by

means of dotted lines, these are merely to avoid obscuring the block supports 7 and it must therefore be borne in mind that the coil is superimposed upon the table surface.

It is obvious that by practicing my invention, it is unnecessary to move the coiI after it has once been formed, until its structure has been made secure by the cord reinforcement. It is also apparent that the coils of hose or the like need not be initially formed upon the table but may be wound by other apparatus and subsequently positioned upon the table only for the winding and tying of the tape 8 thereon to complete the bundle. A bundle made in the manner heretofore described has suflicient body to withstand the vibration and rotary motion imparted thereto by a wrapping machine. Moreover, I have obviated the former difficulty of single turns of hose slipping out of position and into the path of the wrapping spindle.

Although I have illustrated a plane surface upon which the hose is coiled, one of trough or concave formation is of course clearly within the scope of the invention and may be employed if so desired. Moreover, while I'have described but a single embodiment of my invention and noted but two minor variations thereof, it will be appreciated by anyone skilled in the art that the invention isnot so limited and I desire, therefore, that its scope be construed in accord-ance with prior art and the appended claims.

1 What I claim is:

1. A device for winding and reinforcing hose preparatory for the wrapping process, comprising a rotatable supporting table composed of a plurality of spaced supporting unitseach defined by an outer wall and a pair of inwardly converging but nonradially extending walls.

2. A device for winding and reinforcing hose preparatory for the wrapping process, comprising a rotatable supporting table composed of a plurality of spaced supp0rting units each defined by an arcuate wall and a pair of inwardly but non-radially extending Walls.

3. A device for facilitating the binding of hose prior to Wrapping, comprising a shaft, a disc mounted on the shaft, a plurality of standards carried b the disc, and a supporting surface former by a plurality\ of segments each mounted upon a standard and separated from each other by inwardly but non-radially extending spaces.

4. A device for facilitating the binding of coil material comprising a table composed of a plurality of segments supported in spaced relation, each segment being defined by an arcuate wall and a pair of straight vertical Walls one of which extends inwardly in a non-radial direction from the arcuate wall.

5. A device for facilitating the binding of coil material preparatory for Wrapping comprising a table composed of a plurality of segments supported in spaced relation, each segment being defined by an arcuate wall and a pair of straight vertical walls extending inwardly in a non-radial direction from the arcuate wall.

6. A device for facilitating the binding of coils of tubular material preparatory for Wrapping comprising a disc supported for rotation about a central vertical axis, a plurality of standards carried by the disc and blocks carried by the respective standards, each block being defined by an arcuate wall and a pair of straight Walls extending inwardly in a non-radial direction from the arcuate Wall.

In witness Whereof,- I have hereunto signed my name.

JORGEN-I. HAASE.
