poration of New York Original-application January 26,-1946, Serial No. 643,732. Divided and this application March 19, 1947, Serial No.-735,818
. 7 claims. (01.154-45) This invention relates to apparatus for use in manufacturing flexible hose, more particularly hose having two or more layers of textile fabric as components of its wall. More particularly it relates to apparatus adapted for use in forming an adhesive bond between any two of such layers according to the method described and claimed in the copending application of Karl Pape, Serial No. 643,732, filed January 26, 1946, of which this application is a division.
According to the method particularly described in the aforesaid parent application, a hose or exible tubing having at least one layer of textile fabric on its outer surface, such as cotton braid for example, is first wetted with water and then coated with powdered polyvinyl alcohol in such an amount as will adhere to the wetted surface. A second layer of fabric is formed over the thus coated surface, forexample by braiding, and the 'hose or tubing is then passed through a chamber in which it is bathed with steam.
IWhile v the apparatus herein described is adapted particularly to carrying out the aforesaid speciflc method, in which the adhesive is polyvinyl alcohol, the solvent therefor being water, it will readily be appreciated that it is equally adaptable for use with other types of comminuted adhesives used in dry form which may require the use of solvents other than water or the vapor thereof.
The present invention resides in the novel elements and combinationsA of elements hereinafter Belleville, N. J., a corthereon at the point 2| where the yarns22 meet vthe tubing. After being braided, the tubing rpasses over a capstan 24 against which it is pressed by a spring-actuated roller 25. Auxiliary rollers 26 may be used to assist in drawing the tubing through the braiding machine. As the tubing 2U leaves the capstan, it passes through a solvent applying device 28 comprising a chamber having an inlet 29 and an outlet 30 for the tubing, a pipe 3|' for introducing solvent vapor into the chamber and another pipe 32 which serves as a drain. This device may be constructed as shown in U. S. Patents 2,262,514 and 2,262,515, issued November 11, 1941, to which reference is made for a more detailed description.
To maintain the tubing 20 under an inflating pressure during the processing, to provide a firm foundation for the braid and press the layers together, one end is connected at 34 ywith a compressed air line 35 by means of a exible hose 36, the applied pressure being shown by a gage 38. It will be understood that the other end of the tubing will be closed to cause the desired lair pressure to build up therein and that the tubing described, certain illustrative embodiments of which are shown in the drawings in which:
Fig. 1 is a diagrammatic representation of apparatus used in the making of hose having two or more layers of textile fabric adhered together; and
Fig. 2 is a vertical central section through that part of the apparatus in which the solvent and powdered adhesive material are applied to the hose, the latter being shown in position therein.
Referring to Fig. 1, the drawing shows certain parts of a common type of braiding machine, including a slotted plate the slots in which determine the travel of carriers l2 which are actuated ln the usual manner by a gear train (not shown). Each carrier holds the usual cylindrical cross-wound spool |5 and is provided with the usual yarn tensioning device I8. The plate l has a central aperture I8 through which passes the tubing 20 to be covered. As is well known.
the carriers, which may vary in number' but of which there are usually at least 24, travel about the tub/ing in such manner as to weave a braid itself at this stage is impermeable to air by virtue vof a non-porous layer.
The tubing entering the braiding machine is shown as having one layer of braid forming its outer surface and a second layer of braid as being applied on top of it. It will be understood, of course, that the process can be repeated as often as may be desired to provide any number of layers of braid.
Before the tubing 20 enters the braiding mechanism, it passes through a wetting and powderapplying device 40 shown in detail in Fig. 2. In passing through the lower part 4|, the tubing is wetted with water or other solvent for the adhesive, supplied from a containerA 42 mounted for vertical movement as, for example, on the pivoted arm 44 so that by lowering the container 42 into the position shown in dotted lines, the liquid contained in the lower part 4| of the device 40 can be drained off in the event the movement of the tubing 20, is stopped for reasons'hereinafter explained. In the upper part 45 of the device 4D, the wetted tubing is coated with a layer of powdered adhesive, which naturally adheres to the moist fabric, and the next layer of braid is formed at the point 2|, sealing the powder between the two layers of braid.
Referring to Fig. 2, the detailed construction of the device 40 is as follows: the lower part 4| comprises a cylindrical chamber internally threaded in its lower end to receive 'a bottom member 50 having a fiat lower surface 5| and a conical upper surface 52. The member 50 has a central aperture sufficient to permit the free pas,- sage of the tubing 20 therethrough and a watertight seal is provided by a soft rubber gasket 54 which may be compressed against the lower surface of member 50 by a threaded annular nut 55 bearing against a metal washer 56. A pipe 58 is screwed into an aperture in the chamber 4l which is positioned below the top of the member 50. A flexible hose 59 connects the pipe 58 with the container 42.
The solvent chamber 4| is externally threaded at its upper end to receive an internally threaded collar 60. This collar is also internally threaded at its upper end to receive a plug 6| forming the bottom of a hopper 62. The plug 6| has a central aperture 64 to permit free passage of tubing 20 and below this aperture is a second rubber washer 65, metal washer 66 and threaded annular collar 61, forming an adjustable seal to prevent the material in the hopper 62 from falling into the chamber 4| and which may be adjustedto remove excess solvent by exerting pressure on the tubing .20. In order to keep the loosely powdered Amaterial 'I0 in the hopper 62 in contact with the tubing 20 at all times, any suitable vibrating device 1| may be provided to be operated electrically or mechanically in a known manner so as to render the powder mobile and cause it to flow into contact with the tubing. y
Operation Tubing having one or more layers of braid on it is pushed up through washer 54, through the chamber 4| and through washer 65 and the hopper 62, chamber 4| being empty at this time. Nut 55 is adjusted with the minimum pressure required to keep liquid from leaking out of the chamber. Nut 61 may be adjusted to give any desired pressure on the tubing. The looser its adjustment the wetter the tubing will be as it enters the hopper. Reservoir 42 is raised to permit liquid to flow into chamber 4| to the desired depth. Because of the rather slow movement of tubing through a braider, it is sumcient if about an inch of water is maintained in chamber 4|, the water level being adjusted by raising or lowering reservoir 42. Because it isnecessary to stop braiders periodically to add yarn spools, chamber 4| should be drained by lowering the reservoir, especially where the hose liner is of polyvinyl alcohol composition, which is affected by water, to prevent excessive or non-uniform wetting of the braid or damage to the liner through the solvent action of excess water.
As tubing 2|) passes upwardly through the device 4|) and the braider, a layer of adhesive powder adheres to its moistened outer surface and a new layer of braid is applied thereover. When this composite article passes through the chamber 28,
solvent vapor is supplied to the adhesive through -the newly applied braid and this, together with the moisture in the underlying braid, exercise a dissolving action on the adhesive powder which becomes strongly adherent to both layers of braid, With the method described the adhesive, since it is not liquefied, does not soak into or impregnate either layer of braid and its adhesive action is therefore limited to the adjacent surface fibers of the two layers of braid, which is the only place where adhesive serves a useful purpose in bonding the layers. As a result, the braid layers maintain most of their original pliability. At the same time, because the concentration of adhesive 4 at the adhered surfaces is much greater than where a solution of adhesive is used, the strength of the bond between layers of braid is very much greater.
It is to be understood that the specific apparatus described above it to be construed merely as an illustrative embodiment of the-invention which is defined in the appended claims and not as a limitation thereof since various changes in details of construction may be made without departing from the spirit of the invention as claimed.
