ABSTRACT:
The present invention relates to gradually applying a slippery agent to resin impregnated cloth for generating a gradient of slippery agent on the cloth whereby the outward most exposed portions of the cloth wound on a pipe have the highest concentration of slippery agent and the concentration of slippery agent decreases with the depth of the cloth wound around the pipe. The method of the present invention comprising the steps of impregnating the cloth with the resin, impregnating the spool with the slippery agent such that the slippery agent is removably engaged with the spool and the slippery agent is uniformly distributed on the spool, receiving the cloth on the spool for generating an assemblage comprising the resin impregnated cloth and the slippery agent impregnated spool such that no mixture of the resin and the slippery agent is effected and the assemblage can be hermetically stored for later use, subsequently activating the resin in the cloth by engaging the assemblage with water, removing the cloth from the spool by receiving the cloth on the pipe, such that the combined effect of activating the resin on the cloth and removing of the cloth from the spool provides that the slippery agent on the spool is gradually applied to the resin impregnated cloth for generating a gradient of slippery agent on the cloth whereby the outward most exposed portions of the cloth received on the pipe have the highest concentration of slippery agent and the concentration of slippery agent decreased with the depth of the cloth wrapped around the pipe. Also, an article of manufacture is provided.
