Abstract
Abstract A continuous length of cold crimp sleeve material is fed past a shear blade towards a stop. A perform die is disposed between the stop and the shear blade and is driven with the shear blade from a press ram. The preform die moves in a reverse direction to the shear blade and shearing and preforming are performed simultaneously. The preformed cut sleeve is transferred laterally to a crimping station where the dies are operated from the ram simultaneously with the shear blade and preform die. A further transfer device driven with the feeding device for the sleeve length transfers cut sleeve lengths from a first transfer part into the dies and presents a stop serving to position the leading end of a crimped termination within the cold crimp sleeve.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
93 words
A method of preparing cold-crimp sleeve lengths from a continuous length of insulating material for insulating a wire termination by the cold-crimp sleeve technique, comprising feeding the continuous length of insulating material to engage an end with a stop at a cutting, measuring and preforming station, severing an end length from the continuous length of insulating material at a predetermined distance from the stop, preforming the cut length at the station, transferring the preformed cut length laterally from the station to a crimping station, and cold-crimping the cut length about a wire termination.
Claim 2
Independent Claim
93 words
A method of preparing cold-crimp sleeve lengths from a continuous length of insulating material for insulating a wire termination by the cold-crimp sleeve technique, comprising feeding the continuous length of insulating material to engage an end with a stop at a cutting, measuring and preforming station, severing an end length from the continuous length of insulating material at a predetermined distance from the stop, preforming the cut length at the station, transferring the preformed cut length laterally from the station to a crimping station, and cold-crimping the cut length about a wire termination.
Claim 3
Independent Claim
93 words
A method of preparing cold-crimp sleeve lengths from a continuous length of insulating material for insulating a wire termination by the cold-crimp sleeve technique, comprising feeding the continuous length of insulating material to engage an end with a stop at a cutting, measuring and preforming station, severing an end length from the continuous length of insulating material at a predetermined distance from the stop, preforming the cut length at the station, transferring the preformed cut length laterally from the station to a crimping station, and cold-crimping the cut length about a wire termination.
Claim 4
Independent Claim
93 words
A method of preparing cold-crimp sleeve lengths from a continuous length of insulating material for insulating a wire termination by the cold-crimp sleeve technique, comprising feeding the continuous length of insulating material to engage an end with a stop at a cutting, measuring and preforming station, severing an end length from the continuous length of insulating material at a predetermined distance from the stop, preforming the cut length at the station, transferring the preformed cut length laterally from the station to a crimping station, and cold-crimping the cut length about a wire termination.
Claim 5
Dependent Claim
93 words
A method as claimed in claim 1, in which additional steps include operating feeding means for the sleeve to position an end of the continuous length against the stop at the cutting, measuring and preforming station and at the same time transferring a cut length of sleeve into the crimping station, inserting a wire termination into the cut length of sleeve at the crimping station, moving a ram to effect a cold-crimping operation at the crimping station, and performing a cutting operation and a preforming operation at the cutting, measuring and preforming station.
Claim 6
Dependent Claim
61 words
A method as claimed in claim 2, in which the preforming step is effected at an end of the cut length of sleeve remote from the stop, and at the crimping station a wire termination is inserted into the cut sleeve against a stop arranged to locate a leading end of the termination at a predetermined position longitudinally of the sleeve.
Claim 7
Dependent Claim
31 words
A method as claimed in claim 2 or in claim 4, in which the preforming includes driving a die in a reverse direction to a shear blade for cutting the sleeve.
Claim 8
Dependent Claim
115 words
A machine for preparing cold crimp sleeve lengths from a continuous length of insulating sleeve material for insulating wire terminations by the cold-crimp sleeve technique, comprising a feed device arranged for step-by-step feeding of a continuous length of cold-crimp sleeve material through a feed passageway in alignment therewith, a slot extending transversely of the feed passageway, a cutting device including a shear blade for movement within the slot for cutting the sleeve at the slot, a preforming die being disposed in the passageway at a side of the shear blade remote from the feed device, and transfer device being arranged for transferring a cut length of sleeve laterally from the passageway to a crimping device.
Claim 9
Dependent Claim
115 words
A machine for preparing cold crimp sleeve lengths from a continuous length of insulating sleeve material for insulating wire terminations by the cold-crimp sleeve technique, comprising a feed device arranged for step-by-step feeding of a continuous length of cold-crimp sleeve material through a feed passageway in alignment therewith, a slot extending transversely of the feed passageway, a cutting device including a shear blade for movement within the slot for cutting the sleeve at the slot, a preforming die being disposed in the passageway at a side of the shear blade remote from the feed device, and transfer device being arranged for transferring a cut length of sleeve laterally from the passageway to a crimping device.
Claim 10
Dependent Claim

A machine as claimed in claim 5, in which another transfer device is provided to advance cut lengths of sleeve axially from the first-mentioned transfer device to the crimping device, the other transfer device providing a wire termination stop for obturating the trailing preformed eNd of the cut length at the crimping device.
Claim 11
Dependent Claim
29 words
A machine as claimed in any of claim 5, in which the preforming die is arranged to operate on the sleeve in a reverse direction to the shear blade.
Claim 12
Dependent Claim
