Abstract
A burning wick for hydrocarbons and the like is manufactured by continuously forming two wick bodies by two juxtaposed raschel knitting machines, and then fastening the two bodies together transversely along spaced lines, by wrap yarns or other linking yarns. The composite strip thus formed is then cut off along those transverse junction lines, to provide a plurality of separate cylindrical sleeves, each of which serves as a wick. The individual knit wick bodies can have various weaves across their transverse width, such as a burning portion at one edge, an intermediate suction portion for drawing up the fuel, and a bending or stretching portion between the edges of the body and characterized by a reduced number of weft yarns. In this way a cylindrical wick is produced which has various characteristics along its axial length.
