Left and Right Coupler belongs to rib peeling roll stamping connection system, it work together with rib peeling roll stamping machine for the connection of rebar whose diameter is between 16mm and 40mm. Left and right thread couplers are used in the condition that the rebars can only be pulled but not be rolled.

Principle:
All process is completed by one machine.
First use the rebar rolling thread machine to process the rebar to make parallel thread;
Second, use the coupler to link the two bars.

Features:
1, Tensile strength of connection point is equal to connected bar's specified tensile strength;
2, Rib peeling completed by one-time steel bar nipping, roll screw thread with fast speed;
3, Highly automatic and easy to operate;
4, Roll stamping after steel bar rib peeling, with good shape of thread, high precision and
Conformed diameter size;
5, Rolling wheel has long service period, low additive cost of connector;
6, Few roll head specifications, wider scope of steel bar machining, Only one set machine
Can process 16mm-40mm screw thread steel bar;
7, Easy to adjust, when rolling steel bars of different specifications, adjustments can be
Made without taking apart rolling head, provided that the screw pitch are the same.
