ABSTRACT:
A jointer for laminated tapes for use in the production of sheathed cables formed by longitudinally or helically wrapping cable cores with metal tapes laminated with plastic films and by joining the overlapped portions of said tapes by way of heat fusion is disclosed. The method comprises the use of pressing blocks consisting of metal material having a high heat conductivity and respectively having machined surfaces opposing in parallel to each other for the application of uniform pressure to both surfaces of the laminated tapes held therebetween. A heating piece is provided which is electrically insulated from and mounted to the bottom of the pressing block and having relatively high electric resistance and being supplied with electric current thereby pulse heating the portions of the laminated tapes to be spliced.
