4. Product type:
4.1 SYS A: Parallel Thread Rebar Splicing with Cold Upsetting End
Principle:
(1) Enlarging ends of reinforced bars by cold upsetting;
(2) Threading parallel threads;
(3) Splicing rebars by coupler.

4.2 SYS B: Parallel Thread Rebar splicing with Rolled Tread End
The technologies of parallel thread rebar splice include directly rolling and Rolling after stripping rib.

Directly rolling:
(1) Cutting off the end of the rebar;
(2) Rolling the end by using the special rolling machine;
(3) Splicing the rebar by using the coupler.

Rolling after stripping rib:
(1) Cutting off the end of the rebar;
(2) Stripping the ribs at the end of the rebar and rolling thread;
(3) Splicing the rebar by using the coupler.
