CA 2233955
The invention features a rubber thread (10) that features in cross-section, two or more rubber portions. One rubber portion can be, for example, the central core (12) of the rubber thread, while a second rubber portion can be a jacket (14) surrounding the central core. The rubber thread comprising the two rubber portions can have a mix of properties, some provided by the first rubber portion, and others by the second rubber portion. For example, in the core/jacket embodiment, the core can be composed of natural rubber, and thus provide the thread with excellent resiliency, and the jacket can be composed of a synthetic rubber that is more resistant to abrasion than natural rubber. The resultant two-portion rubber thread will, therefore, benefit from the characteristics of both components. The invention also features a method of making a rubber thread that has in cross- section two rubber portions.
