APPARATUS FOR THE PRODUCTION OF PLASTIC PIPES |
摘要 |
Pipes with special profile sections are produced by an apparatus with circuit guided half shells. The half shells combining to form a mold have mold walls extending about parallel to a mold space axis. Vacuum slits extend about parallel to the mold space axis to open into a mold space in each case at a place radially the most distant from the mold space axis.
