TYING REINFORCING BAR : 'THE REBAR TYING MACHINE' CAN REMEDY THEINCONVENIENCE

I stumbled upon this machine while doing some normal browsing. Manually tying rebar with pliers increases risk of developing any arm related disorder. ‘The Rebar Tying Machine’ can significantly decrease the time to tie rebar, which in turn can improve productivity and enhance safety.
