Abstract
Abstract A process and device for tying metal reinforcement and/or mesh structures wherein U-shaped clips having bent and generally diverging arms are placed at the crossings of the rod to be tied together and engage twice on each of the rods of the crossing, the arm ends being closed by being twisted until a portion of the ends ruptures, the twisting being performed by a substantially longitudinal tool having at the front jaws which in the open state close on the clip ends, turn and twist the same and finally break the ends leaving them twisted, the jaws returning to the same initial position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A device for the binding of intercrossing elements comprising a clip having a general U shape including a circular base portion; arms extending from opposite ends of said base portion to free ends at the ends of each of said arms; each of said arms having an intermediate bent elbow along said arm; a first straight portion between said elbow and said base portion; a second straight portion between said elbow and said free end of said arm; a recess along said arm in proximity to said free end, acting as a breakaway point; said clip positioned relative to said intercrossing elements with said base portion and a portion of said arms extending from opposite ends of said base portion extending around one of said intercrossing elements; said intermediate bent elbows of both said arms cradling another of said intercrossing elements; portions of each of said arms extending from said intermediate bent elbows to said free ends passing on opposite sides of said one of said intercrossing elements; said free ends extending beyond said one of said intercrossing elements for forming twisted free ends against said one of said intercrossing elements.
Claim 2
Independent Claim
191 words
A device for the binding of intercrossing elements comprising a clip having a general U shape including a circular base portion; arms extending from opposite ends of said base portion to free ends at the ends of each of said arms; each of said arms having an intermediate bent elbow along said arm; a first straight portion between said elbow and said base portion; a second straight portion between said elbow and said free end of said arm; a recess along said arm in proximity to said free end, acting as a breakaway point; said clip positioned relative to said intercrossing elements with said base portion and a portion of said arms extending from opposite ends of said base portion extending around one of said intercrossing elements; said intermediate bent elbows of both said arms cradling another of said intercrossing elements; portions of each of said arms extending from said intermediate bent elbows to said free ends passing on opposite sides of said one of said intercrossing elements; said free ends extending beyond said one of said intercrossing elements for forming twisted free ends against said one of said intercrossing elements.
Claim 3
Independent Claim
103 words
A device for the binding of intercrossing elements comprising a clip having a general U shape including a circular base portion; arms divergently extending from opposite ends of said base portion to free ends at the ends of each of said arms; each of said arms having an intermediate bent elbow along said arm; a straight portion between said elbow and said free end of said arm; said free ends adapted for being twisted together; and terminal bends, along said arms between said bent elbows and and said free ends, before said free ends, with said bends converging said arms toward each other.
Claim 4
Independent Claim
103 words
A device for the binding of intercrossing elements comprising a clip having a general U shape including a circular base portion; arms divergently extending from opposite ends of said base portion to free ends at the ends of each of said arms; each of said arms having an intermediate bent elbow along said arm; a straight portion between said elbow and said free end of said arm; said free ends adapted for being twisted together; and terminal bends, along said arms between said bent elbows and and said free ends, before said free ends, with said bends converging said arms toward each other.
Claim 5
Dependent Claim
28 words
The device for the binding of intercrossing elements according to claim 2 wherein said terminal bends are divergent along said arms from said bends toward said free ends.
Claim 6
Independent Claim
91 words
A device for the binding of intercrossing elements comprising a clip having a general U shape including a circular base portion; arms divergently extending from opposite ends of said base portion to free ends at the ends of each of said arms; each of said arms having an intermediate bent elbow along said arm; a straight portion between said elbow and said free end of said arm; a recess along said arm in proximity to said free end, acting as a breakaway point; said free ends adapted for being twisted together.
Claim 7
Independent Claim
91 words
A device for the binding of intercrossing elements comprising a clip having a general U shape including a circular base portion; arms divergently extending from opposite ends of said base portion to free ends at the ends of each of said arms; each of said arms having an intermediate bent elbow along said arm; a straight portion between said elbow and said free end of said arm; a recess along said arm in proximity to said free end, acting as a breakaway point; said free ends adapted for being twisted together.
