Abstract (en)
This invention provides an improvement in the block incorporating a series of spinning heads for spinning plastic masses to obtain synthetic yarn, and specifically relates to a block with the spinning heads, one following another, spaced equally and sufficiently apart to generate a perfect distribution of the heating vapour about each individual spinning head, which is hence heated to a strictly uniform temperature in each of its parts, this temperature being precisely the same for each of the spinning heads incorporated into the spinning block. <IMAGE>
