DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Figures I through 3 there is shown a form of apparatus of the present invention for fabricating bundling means. An elongated resilient tubular member 2 is shown being processed by the apparatus 4. The apparatus 4 includes a base portion 6, an upper portion 8, and R connecting portion 10. In this embodiment, the apparatus portions 6, 8, 10 provide a rigid generally channel shaped mcmber whlch defines an 20 opening 14 within which the tube 2 is received.
The apparatus 4 also is provided with support means which serve to support the pipe 2 in the desired position during processing. In the form shown, the support means consists of four upper rollers 18, 20, 22, 24 which depend downwardly from the upper portion 8. The rollers are so mounted ` ' ' .
:. :
~ - `
that they are adapted to rotate about an axis which is oriented generally parallel with respect to the longitudinal central axis A of tube 2~ It is noted that a first pair of upper rollers 18, 20 are disposed on one side of the longitudinal central axis A and are disposed in generally aligned position. A
second pair of upper rollers 22, 24 are disposed on the other side of central axis A and are in generally aligned position. Rollers 20, 22 are disposed generally at the same axial position and rollers 18, 24 are disposed at the same generally axial position.
In the form shown in Figures 1 through 3 the lower support means consists of four rollers mounted for rotational movement about an axis oriented generally parallel to the longitudinal axis A. A first pair of rollers 30, 32 is disposed on one side of the axis A and in generally aligned relationship. A second pair of rollers 34, 36 is disposed in generally aligned relationship on the other side of the axis A. Rollers 30, 34 are disposed in generally the same axial position and rollers 32, 36 are disposed at generally the same axial position as each other.
In the form illustrated the spacing between the rollers of a pair of rollers (30, 34, or 32, 36) on the base portion 6 is preferably slightly greater than the spacing between the rollers of a pair of rollers (20, 22, or 18, 24) on the upper portion 8.
The apparatus also has a blade 40 which extends downwardly into the channel opening 14. It is noted that the blade 40 has a tapered free end which extends suft`iciently far into the opening 14 so as to be adapted to pass completely through the wall of tube 2. In order to permit the apparatus to be used in cutting different pitch angles, the blade 40 in the form shown is adapted to be rotated by means of operating knob 42 which is connected to the blade by spindle 44 which passes through upper portion 8.
Knob 42 is preferably prevented from rotating during cutting so as to maintain the desired cutting angle. This may readily be accomplished by means of a suitable locking screw, (not shown) for example.
In effecting processing of the tube 2 relative movement is established between the tube 2 and the blade 40. In a preferred form o~ the present invention a handle 48 (Figures 2 and 3) is secured to the connecting portion lO so as to permit the apparatus 4 to be moved with respect to a 10 stationary pipe so as to sequentially generate a helical cut 50.
Alternatively, the pipe may be moved rotationally and longitudinally in the direction shown by the arrow in Figure l, for example, with respect to the stationary apparatus 4.
It will be appreciated therefore that in using the apparatus and method of the present invention bundling means may be fabricated by providing an elongated resilient member such as tube 2 and sequentially establishing a substantially continuous helical slit in the wall of the tube.
Referring now to Figure 4 there is shown A section of resilient tube which has been processed by the apparatus and method of the present 20 invention. The pipe has an external diameter Dl with a substantially continuous helical slit 52 completely through the wall of the tube. The wall portion between the next adjacent pair of slit portions such as 52a and 52b will be considered the pitch-P. The pitch P may conveniently be about 30 to 90 percent of the tube diameter and preferably about 60 to 80 percent thereof. In effect, the pitch refers to the width of a particular wrap. The ...... ~ ~.
41 7~
~112151 pitch angle B is the lesser angle between the slit and the plane of the surface on which the pipe is resting. In a preferred form of the invention this is about 60 to 85 degrees and in the preferred form is about 74 to 84 degrees.
Referring now to Figures 5 and 6 there is shown the bundling means in resiliently radially expanded position in circumferential surrounding relationship with a plurality of elongated articles which may be hoses or electrical cables 60, for example. It will be appreciated in the expanded relationship the bundling means 58 has been enlarged to a 10 diameter D2. The preferred form of the invention the diameter Dl of the unexpanding bundling means 58 is not more than about twenty-five to seventy-five percent of the diameter D2 of the expanded bundling means 58 and preferably about forty to fifty percent. In this fashion, the inherent resiliency and the freedom to expand generated by the helical slit 52 permit firm resiliently maintained retention of the elongated articles 60.
It will also be appreciated that the bundling means may consist of a single continuous element such as 58 or a series of smaller elements spaced longitudinally along the length of the elongated articles 60. If desired, bundling means anchoring (not shown) may be provided to secure the 20 bundling means 58 to a portion of a piece of equipment. This may readily be accomplished by simple fasteners or anchor clips.
In a preferred embodiment the pipe 2 will be made of a resinous material such as polyethylene having an external diameter of about one half to three inches and a wall thickness of about one eighth inch.

~112151 Referring now to Figures 7 and 8 a further embodiment of the invention will now be considered. In order to improve the versatility of the equipment and method, it may be desired to provide adjustment means so as to permit spacing adjustments between either the upper support means and the lower support means or within a given tier of support means. In the embodiment shown in Figure 7, the base 6' supports four upwardly extending rollers 64, 66 (two rollers are not shown in this view) and the upper portion 8' supports four downwardly extending rollers 68, 70 (two rollers not being shown in this view). The connecting means 10' is divided into a lower sector lOa and an upper sector lOb with the connection being made by an adjustment screw 72 or two or more spaced adjustment screws if desired. A thumb screw head 74 is provided as a means for effecting desired adjustment.
Referring to Figure 8 it is seen that a base or upper portion 78 may be split so as to carry a pair of rollers on each segment 78a, 78b with adjustment being effected by two or more spaced adjustment screws 80, 82.
While for clarity of disclosure reference has been made herein to establishing relative movement between the tube and blade without express limitation to a speclfication of either manual or automatlc means.
In addition to the specific means disclosed hereinabove various automated means will be readily apparent to those skilled in the art. An example of a suitable automated means is shown in Figure 9. Apparatus 100 has gear 102 operatively engaged with gear 104 which in turn is driven by motor 106 through shaft 108. In the form shown gear 102 supports rollers ~,~.._ ., . . . ~

It will therefore, be appreciated that the present invention has provided economical means for fabricating bundling means in order to permit resiliently maintained retention of a plurality of elongated articles.
All of this is accomplished by preserving simplicity of fabrication with relatively inexpensive equipment which may be either manually or 10 automatically operated. In addition, in preferred embodiments adjustment means are provided so as to provide the system to be used with bundling means of various sizes.
Whereas particular embodiments of the invention have been described above for purposes of illustration it will be evident to those skilled in the art that numerous variations of the details may be made without departing from the invention as defined in the appended claims.
