Abstract
The head box guide is formed of a metal block with cylindrical bores into which a pair of telescoping plastic inserts are fitted. Each pair of inserts are formed so as to define a stepped widening within the block. In addition, the inserts have terminal parts which are disposed outside of the bores and which are locked together in contiguous fashion so as to avoid any gaps. Also, a honeycomb connecting member rests on the downstream terminal parts of the inserts to form continuations of the flow passages.
