Abstract

A conveyor belting, e.g., for transporting dough or paste in the food industry comprises a fibrous facing material 2 and a flexible backing material 3, there being a vulcanisable material 4 placed between the two and whereby the facing material and the backing material can be vulcanised together. <IMAGE>

Description

SPECIFICATION Belting This invention relates to conveyor belting, particularly though not necessarily exclusively, for use in the food industry.
In the production of food products such as bread or pastry, the dough, paste or the like is normally batch produced, portions of the correct weight being severed from the batch and conveyed to a location where, e.g., shaping takes place or the placing of the severed portion in an appropriate baking tin or case.
To convey the severed portion, it has been usual hitherto, to utilise a conveyor belt formed with an upper surface of a felt-like material secured by adhesive to a single or multiply cotton backing with oversewing to assist in securing the upper felt to the cotton backing and increase the frictional effect between the upper surface and the product.
Whilst such conveyors have proved adequate in the transport of the dough or paste product, giving reasonably good release at the end of the conveyor run and being cleanable, they have been found to have only a short working life. Dough or paste by its very nature contains oil and it has been found that the oil attacks the adhesive between the felt upper and cotton backing causing the felt to part from the backing, and the oversewing has been found not to be strong enough to hold the two together in the absence of the adhesive. This has led to the need for relatively frequent replacement of belts at the cost involved.
The object of the present invention is to provide a construction of conveyor belt that substantially eliminates the problems outlined above.
According to the present invention, belting comprises a fibrous facing material and a flexible backing material, there being a vulcanisable material placed between the two and whereby the facing material and the backing material can be vulcanised together. For simplicity of manufacture, it is preferred that the vulcanisable material is a vulcanising film that can simply be laid on the backing material and overlaid by the facing material. It is further preferred to oversew the belting in conventional manner, not to assist in holding the facing material to the backing material, but to increase the frictional effect between the facing material and the dough or paste deposited on the belting, it being common practice to roll the dough or paste pieces on the belting.
The side edges of the belting can be sealed simply by running a hot iron over the edge, thereby avoiding the fraying at the edge that frequently occurs with conventional belting. Thus, the belting of the invention has the advantage that being a vulcanised construction, it is virtually impossible for the backing to be parted from the facing thereby increasing considerably the life of the belting, however this kind of belting can be still further improved.
According to a further feature of the invention, belting comprises a fibrous facing material vulcanised to a flexible backing material, by means of a vulcanisable material interposed between the facing material and the backing material, opposite, longitudinal edges of the belting being provided with strips of vulcanisable material vulcanised to the longitudinal edges.
Thus, in addition to the facing material being vulcanised to the backing material, the belting can be provided with vulcanised edges and the vulcanising film laid between the facing and backing materials may be employed for the edge strips.
Whilst a conventional felt can be utilised as the facing material, this can have the disadvantage that having a relatively deep pile, fibres can attach themselves to the product, and to avoid this grinding of the surface should be performed at the extra cost involved. It is therefore preferred to use a very short pile polyester yarn or fibre as the facing material, or to use single ply or double ply cotton as the facing material. As to the backing again a single ply or double ply cotton backing can be utilised, but it is preferred to utilise a backing formed from an admixture of nylon and polyester. In either form, the backing may have a plastics facing on the side on which the vulcanising material is laid.
The invention has the advantage that being a vulcanised construction, it is virtually impossible for the backing to be parted from the facing thereby increasing considerably the life of the belting.
One embodiment of the invention will now be described with reference to the accompanying drawing which is a schematic perspective view of part of a belt according to the invention, with parts broken away for clarity.
In the drawing, a belt 1 has a fibrous facing material 2 and a flexible backing material 3 with a vulcanisable film 4 laid between the two, and whereby the facing material is secured to the backing material by vulcanisation. To seal the longitudinal edges of the belting, strips 5 of vulcanisable film are provided to provide vulcanised edges to the belting to guard against fraying. The material for the facing may be very short pile polyester yarn or fibre, or single or double ply cotton and the material of the backing may be single or double ply cotton but is preferably an admixture of nylon and polyester.
1. Belting comprising a fibrous facing material and a flexible backing material, there being a vulcanisable material placed between the two and whereby the facing material and the backing material can be vulcanised together.
2. Belting as in Claim 1, wherein the vulcanisable material is a vulcanising film that is laid on the backing material and overlaid by the facing material.
3. Belting as in Claim 1 or Claim 2, wherein the belting is oversewn to increase the frictional effect between the facing material and dough or paste deposited on the belting.
4. Belting as in any of Claims 1 to 3, wherein the side edges of the belting are sealed simply by running a hot iron over the edge, thereby avoiding the fraying at the edge that frequently occurs with conventional belting.
