Abstract
A process produces an electrical line which extends in the longitudinal direction and the line has a line core and an outer shell. In a continuous shaping process, individual shell portions of the outer shell are formed successively by surrounding the line core with a curable plastic substance. In at least one portion, the outer shell is produced having a cross-sectional geometry which can be varied in the longitudinal direction of the line.
Claims20
A process for producing a line extending in a line longitudinal direction and having a line core and an outer shell surrounding the line core, which comprises the steps of:
- forming the outer shell from individual shell sections directly adjoining one another, the individual shell sections of the outer shell being formed, in a continuous molding process by a tool mold, in successive fashion by virtue of the line core being surrounded with a solidifiable plastics compound, wherein, in at least one subsection, the outer shell is produced with a varying cross-sectional geometry varying in the line longitudinal direction.
A line extending in a line longitudinal direction, the line comprising:
- a line core;
- and
- an outer shell surrounding said line core, said outer shell having a cross-sectional geometry varying in the line longitudinal direction, said line core running in elongate fashion along a longitudinal axis.
A tool mold for producing a line extending in a line longitudinal direction and the line having a line core and an outer shell surrounding the line core, the tool mold comprising:
- a molding module formed as a divisible extrusion nozzle and having a mold cavity with a variable cross-sectional geometry and a feed opening for feeding of the line core.
