Definitions
- the present invention relates to an apparatus for the production of flexible tubes or hoses provided with a helically extending reinforcing element for instance in the form of a metal Wire, a nylon mcnofil or the like.
- the material of the tube may be arbitrarily chosen provided it is weldable. Preferable various types of plastic materials are used.
- Flexible tubes or hoses at present are used for many purposes such as for supplying air in drying plants.
- Such hoses preferably ought to have a certain stiffness in spite of its flexibility and this is obtained either by producing the wall of the hose from a more or less self supporting material as for example plastic-covered canvas or producing them from a thin material which is stiffened by means of a helical reinforcing.
- Usually such reinforcing element has been secured on the outside or the inside of the tube by means of stitching.
- the invention has for its object to make it possible to produce reinforced tubes or hoses of flexible material in a simplified way, whereby still is obtained very good products.
- FIG. 1 shows an apparatus for the production of reinforced tubes or hoses according to the invention.
- FIG. 2 shows a detail of FIG. 1 as seen from above.
- FIG. 3 shows how the edge joint and insertion of the reinforcing element is carried out.
- a strip 3 of weldable flexible material via a guide roller 5 is led over a rotatable winding drum 1.
- a brake 6 cooperates with the supply roll 4 to regulate the winding off of the strip 3.
- a nylon thread 7 is led over a guide roller 9, on which acts a braking leaf spring or the like to give the thread 7 the desired tightening.
- the nylon thread is then led over the same guide roller 5 as the strip 3 and strip and thread are then both led to the winding drum. 1 in correct mutual position.
- the winding drum 1 is provided with a circularly extending groove 11 adapted to take up the nylon thread 7 and that part of the strip edge which is located under said thread as further explained below.
- the wind ing drum 1 cooperates with a welding electrode wheel 10.
- the strip 3 is wound up in overlapping position to form a tube or hose, said overlapping edge portions being welded together.
- the apparatus is so adjusted that the nylon thread 7 during the welding operation is situated in about the middle of the overlapping edge portions, which thereby is welded together on both sidm of the the producthread.
- the nylon thread thus will be situated in the interior of a helically extending canal in the wall of the finished tube or hose.
- FIG. 3 is shown in an exaggerated form how the thread 7 is located in the groove 11 of the drum 1 during the welding operation.
- the groove 11 is thus dimensioned to take up the thread 7 as well as that part 16 of the edge of the strip 3, which is located partly around the thread in the groove.
- the thread Will be located in a canal extending on the inner side of the wall of the tube or hose. The outside of the tube or hose is even.
- the feed of the finished tube or hose 14 in its axial direction is adjustably carried out by means of the guide roller 2, which is arranged having its axis of rotation oblique in relation to the axis of the winding drum 1 and being provided with a groove 13 adapted for the reinforcing thread.
- This guide roller 2 thus will feed the finished product 14 axially away from the drum 1 by means of the engagement between the thread-and-edge portion 7, 16 and the groove 13.
- the adjustment of the inclination of the axis 12 in relation to the axis of the winding drum 1 will regulate the feed and thereby also the overlapping of the two edge portions of the strip which are to be welded around the reinforcing element 7.
- Apparatus for continuously forming flexible hose of the wire reinforced type having tape disposed helically in overlapping relationship comprising a winding drum and a guide roller disposed adjacent one another on axes extending at an acuate angle to each other in parallel planes, said winding drum having a pair of annular grooves at the periphery thereof in planes extending in spaced relationship normal to the drum axis, said guide roller having an annular groove at the periphery thereof in a plane extending normal to the roller axis, drive means for rotating each of said drum and said roller through engagement with a corresponding end of each, the other end of each of said drum and said roller being free and unobstructed, means for feeding the tape and the wire onto the drum with one edge of the tape in overlapping relationship with the Wire in the drum groove remote from said free end thereof, whence the tape and the wire pass onto the roller with the wire and said edge in overlapping relationship in the groove thereon, said roller extending in the space between said planes of the drum grooves in such
