Patent ID: 8663521

Claim:
A process of manufacturing a looped material band ( 1 ) in which ends of the band are assembled by fitting together two serrations ( 2 a , 2 b ) having complementary shapes provided respectively in a plane of each of the ends ( 1 a , 1 b ), and teeth ( 2 c ) of each serration ( 2 a , 2 b ) comprising at least one transversal opening ( 2 d ) that is aligned with the at least one transversal opening ( 2 d ) of neighboring teeth ( 2 c ) so as to define, when the serrations ( 2 a , 2 b ) are fitted together with one another, at least one transversal passage ( 8 ) for receiving at least one locking rod ( 3 ) of a junction, the process comprising the steps of: machining the ends ( 1 a , 1 b ) of the band ( 1 ) to remove material in an area corresponding at least to the transversal openings ( 2 d ) to be produced; cutting the teeth ( 2 c ) to form the serrations ( 2 a , 2 b ) after machining the ends ( 1 a , 1 b ) of the material band ( 1 ); fitting the serrations ( 2 a , 2 b ) with one another; disposing a transversal core pin ( 7 ) in each machined area; overmolding material in the machined area to restore the ends ( 1 a , 1 b ) of the band ( 1 ); removing each transversal core pin ( 7 ), forming each transversal opening ( 2 d ), after polymerization of the material; separating the serrations ( 2 a , 2 b ) by die-stamping after the overmolding step; and stamping the material band ( 1 ) at an exact location where the serrations ( 2 a , 2 b ) were previously cut using the same stamping die.
