Abstract
A rubber belt comprising at least one layer of a plurality of tightly packed elastic yarns or fibers and at least one layer of silicone rubber. A method of manufacturing a rubber belt is also disclosed. The method comprises the steps of wrapping one or more elastic yarns or fibers onto a mandrel, where the one or more elastic yarns or fibers form one or more layers on the mandrel; adding a liquid high viscosity silicone rubber on top of the one or more layers; and heating the mandrel in order to polymerize the silicone rubber.
Claims16
A rubber belt comprising:
- a single layer formed substantially by a plurality of tightly packed elastic yarns or fibers provided by wrapping a single elastic yarn or fiber around a mandrel or two parallel rolls, the fiber extending in a machine direction (MD),
- wherein said elastic yarns or fibers have an elongation at breaking point between 40 and 400% of their original length, and further
- wherein each of the plurality of tightly packed elastic yarns or fibers are in contact with at least one adjacent elastic yarn or fiber associated with the plurality of tightly packed elastic yarns or fibers within the formed layer;
- and
- at least one layer of silicone rubber,
- wherein a width of said elongated rubber belt remains substantially unchanged in a cross machine direction (CD) when said belt is elongated in said machine direction from 50 to 70% of the belt's original length, and
- wherein a first side of one of the at least one layer of silicone rubber is in contact with a textile being formed thereon, and a second side of one of the at least one layer of silicone rubber, which is a side opposite to the first side of one of the at least one layer of silicone rubber, is in contact with the plurality of tightly packed elastic yarns or fibers extending in the machine direction (MD).

A method of manufacturing a rubber belt comprising the steps of:
- wrapping one or more tightly packed elastic yarns or fibers provided by wrapping a single elastic yarn or fiber around two substantially parallel rolls spaced a distance apart from each other in a machine direction (MD), wherein said one or more tightly packed elastic yarns or fibers form a single layer on said two substantially parallel rolls, and wherein each of the plurality of tightly packed elastic yarns or fibers are in contact with at least one adjacent elastic yarn or fiber associated with the plurality of tightly packed elastic yarns or fibers;
- adding a liquid high viscosity silicone rubber on top of said single layer;
- and
- heating said two substantially parallel rolls and said added liquid silicone rubber in order to polymerize said silicone rubber, and
- wherein a first side of the silicone rubber is in contact with a textile being formed thereon, and a second side of the silicone rubber, which is a side opposite to the first side of the silicone rubber, is in contact with the plurality of tightly packed elastic yarns or fibers extending in the machine direction (MD).
