J. HORNSBY May 13, 1941.
CONVEYER BELTING Filed Sept. 5, 1939 Patented May 13, 1941 2,242,128- CONVEYER BELTIN G John Hornsby, London, England, assignor toBritish Belting & Asbestos Limited, London, England, a British company Application September 5, 1939, Serial No. 293,501 In Great Britain September 9, 1938 Claims.
This invention relates to conveyer belting and is particularly concerned with improvements in textile belting for use more particularly for conveying coal and other materials.
The invention has for its object to provide an improved form of textile belting which will be resistant to wear and tear for much longer periods than the belting heretofore used for conveying purposes.
According to the present invention, woven textile belting for conveying coal and other materials is provided with pile threads extending from one or both faces of the belting, which pile threads are rubberized or treated with a suitable binding medium and pressed to produce a consolidated cushioning layer.
Advantageously the belting is treated with latex and the pile threads are rolled down to provide the consolidated cushioning layer on one or both faces of the belting.
The term latex used herein includes rubber or other suitable latex or an equivalent artificial dispersion of rubber or the like having similar properties to latex.
The invention also includes woven textile conveyer belting having on one or both faces a pile formed by uncut loops of thread, such pile being impregnated and/ or coated with latex and being pressed to produce a consolidated cushioning layer which is thereafter vulcanised.
Preferably the whole of the belting is im pregnated with latex and is stretched at the same time as the pile is rolled down.
The invention is hereinafter described by way of example with reference to the accompanying diagrammatic drawing, in which Figure 1 is a diagram illustrating one method of forming the pile;
Figure 2 is a view similar to Figure 1 illustrating the manner in which the pile is formed in the case of a self-binding structure;
Figure 3 is a side elevation illustrating the consolidation of the pile after impregnation; and
Figure 4 is a perspective view illustrating one form of textile belting produced according to the invention.
In carrying the invention into effect according to one embodiment and with reference to the accompanying diagrammatic drawing, woven textile belting I in which binding threads 2 are employed is provided with slack threads 3 in the surface plies arranged to form loops 3a at one or both faces of the belting to form a so-called pile. Preferably the pile loops 3a are left uncut as shown and after impregnation of the belting with straight latex are given a coating of vulcanizing latex. The pile is then rolled down, as shown in Figure 3, to form a consolidated cushioning layer 21), the belting afterwards being calendered and vulcanised by passing through a hot chamber.
In the case of a self-binding structure as illustrated in Figure 2, the pile loops 3a are formed by additional threads 3b.
The threads forming the pile preferably are of a coarse character approximating to thin string and, owing to their being pressed down in the loose condition after treatment with latex, form a cushioning layer which is very resilient.
The cushioning effect of the pile on the conveying surface prevents abrasion and cutting of the belting by the coal or other materials being conveyed, while the provision of the cushioning layer on the other or running face serves to prevent cracking of the belting, and it has been found that belting made in accordance with the present invention is much more resistant to wear than textile belting of the kind usually employed, and is not subject to such reduction in width during use as is encountered in ordinary rubber faced conveyer belting.
More particularly where hot material is to be conveyed, the pile on one or both faces may be formed of asbestos yarn. The pile formation of asbestos yarn provides an effective insulating and protective cover for the cotton weft in the face plies of the belting so that it is unnecessary to employ asbetsos weft throughout.
Advantageously very absorbent thick threads are provided on the selvedges so as to form small loops which provide a protective cover for the weft at the edges. As shown in Figure 4, the selvedge protection may be in the form of a braided tubular banding and may be of cotton or asbestos according to the purpose for which the belting is to be used.
It will be understood that the invention is not limited to the particular embodiment hereinbefore described. Furthermore, the treatment of the belting with latex or other suitable binding medium and the subsequent operations may be carried out in any suitable manner.
I claim:
1. Woven textile conveyer belting for conveying coal and other materials comprising a Woven body having a resilient cushioning layer on at 7 least one face thereof comprising pile threads ing medium and being disposed in overlapping recumbent position against the face of the body and adhesively bonded to each other and to said body by a resilient bonding medium.
2. Woven textile belting for conveying coal and other materials comprising a woven body structure having pile threads extending from at least one face thereof, said pile threads being rubberized and disposed in recumbent position forming a consolidated cushioning layer on the face of said body.
3, Woven textile conveyer belting for conveyvulcanized latex and being disposed in overlapping recumbent position against the face of said body and bonded thereto by vulcanized latex forming a consolidated cushioning layer over the entire face of said body.
4. Woven textile conveyer belting comprising a woven body having uncut looped pile threads extending from at least one face thereof, said looped pile threads being disposed in overlapping recumbent position against the face of said body and bonded thereto by an impregnating layer of vulcanized latex.
5. Woven textile conveyer belting according to claim 4 in which said looped pile threads are formed of asbestos yarn.
