Method for making blanks for parts of pliers

A method of manufacturing blanks for metal components of pliers wherein the blank includes a jaw and an extending heelpiece, wherein each blank is cut out from a respective length of profile of shape of variable thickness the cross section of which corresponds to at least one substantially longitudinal cross section of the blank, and wherein said step of cutting out includes cutting a first portion of said profile of variable thickness to form the jaw and cutting a second portion of said profile of variable thickness to form the heelpiece and wherein the second portion is of a lesser thickness than said first portion of said profile of variable thickness.

A method of manufacturing a half pair of pliers, wherein:

• in order to produce a blank which comprises a jaw and a pliers arm core, an outline of the blank is cut out from a respective length of profile of shape of variable thickness, the cross section of which corresponds to at least one substantially longitudinal cross section of the blank;
• and
• overmolding a pliers handgrip onto said arm core.

A strip of material from which blanks of metal components for pliers can be cut which includes a profile of shape of constant cross section and yet variable thickness which profile of shape is adapted to be cut out to form the blanks of metal components of the pliers and which blanks have at least two portions of different thickness and with one of said portions including a jaw component.

A method of manufacturing blanks for metal components of pliers comprising a jaw, wherein each blank is cut out from a respective length of profile of shape of constant transverse cross section and variable thickness, the transverse cross section of said length of profile of shape corresponding to at least one substantially longitudinal cross section of the blank, and said length of profile of shape being made from a single piece of material.

A method of manufacturing blanks for metal components of pliers comprising a jaw, wherein an outline of each blank is cut out from a respective length of profile of shape of variable thickness, the cross section of which corresponds to at least one cross section of the blank wherein starting from a basic section piece which has a different cross section from the length of profile of shape, at least one forging operation is used to form said basic section piece into localized lengths of profile of shape, and the cutting-out is performed in each of said localized lengths.

A method of manufacturing blanks for metal components of pliers comprising a jaw, wherein each blank is cut out from a respective length of profile of shape of variable thickness the cross section of which corresponds to at least one substantially longitudinal cross section of the blank, wherein the length of profile of shape has, on one side, over its entire extent, a flat face for resting on a flat cutting-out die.

A method of manufacturing blanks for metal components of pliers comprising a jaw, wherein each blank is cut out from a respective length of profile of shape of variable thickness the cross section of which corresponds to at least one substantially longitudinal cross section of the blank, wherein the length of profile of shape has at least one change-of-thickness surface which is inclined with respect to a direction perpendicular to the mid-plane of said length.

A method of manufacturing blanks for metal components of pliers comprising a jaw, wherein an outline of each blank is cut out from a respective length of profile of shape of variable thickness, the cross section of which corresponds to at least one cross section of the blank wherein the length of profile of shape includes at least one shoulder substantially perpendicular to a mid-plane thereof.
