ABSTRACT:
The flexible starter bar has a body which comprises a flexible substantially planar spine on one side, a series of blocks attached to the spine on the other side, and in a top portion thereof adjacent a head for the starter bar, a plurality of block supports disposed between adjacent pairs of blocks adapted to protrude from one block of a pair so as to lie in abutting and supporting relationship with the other block of the pair, thereby increasing the effective length of the operatively outer side of the starter bar body so that the starter bar may assume a curved configuration and be self-supporting. The block supports in the top portion of the starter bar are retractable to shorten the effective length of the starter bar body on the operatively outer side so that the starter bar may resume a straight configuration. The bottom portion of the starter bar is without any block supports and is supported in the curved configuration by a strand guide and support rolls.
