Abstract

Abstract A conventional lead straightener is modified to remove flash from electrical components in addition to straightening leads. The rubber rollers and shoes between which the leads of a component are rolled in the conventional lead straightener are modified by the addition of metal inserts which crush the flash from the lead. The metal inserts are positioned at an angle to the rollers such that the leads maintain contact with rubber when engaged by the metal inserts.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 85 words
An apparatus for removing flash from a lead comprising: a rotatable drum having a resilient layer thereon; a shoe having a resilient layer thereon for cooperating with the drum to roll the lead therebetween; a rigid rib on the drum exposed through the surface of the resilient layer on the drum; and a rigid rib on the shoe exposed through the surface of the resilient layer on the shoe for cooperating with the rigid rib on the drum to crush the flash from the lead.
Claim 2
Independent Claim 85 words
An apparatus for removing flash from a lead comprising: a rotatable drum having a resilient layer thereon; a shoe having a resilient layer thereon for cooperating with the drum to roll the lead therebetween; a rigid rib on the drum exposed through the surface of the resilient layer on the drum; and a rigid rib on the shoe exposed through the surface of the resilient layer on the shoe for cooperating with the rigid rib on the drum to crush the flash from the lead.
Claim 3
Dependent Claim 50 words
An apparatus as defined in claim 1, wherein: the rib on the drum and the rib on the shoe are elongated and at an angle to the axis of the drum such that the lead is always engaged by the resilient layers while being rolled between the drum and shoe.
Claim 4
Independent Claim 99 words
An apparatus for removing excess plastic material and straightening the leads of an axial component, comprising: a rotatable shaft; a pair of equal diameter drums mounted on the shaft and having resilient surfaces formed thereon; a pair of arcuate shoes having resilient surfaces thereon and each shoe mounted for cooperating with a respective drum to roll a respective lead therebetween; a plurality of metal ribs spaced on the surfaces of each drum; and a metal rib on each shoe for cooperating with the metal ribs on the respective drum to break the excess plastic material from a respective lead.
Claim 5
Independent Claim 99 words
An apparatus for removing excess plastic material and straightening the leads of an axial component, comprising: a rotatable shaft; a pair of equal diameter drums mounted on the shaft and having resilient surfaces formed thereon; a pair of arcuate shoes having resilient surfaces thereon and each shoe mounted for cooperating with a respective drum to roll a respective lead therebetween; a plurality of metal ribs spaced on the surfaces of each drum; and a metal rib on each shoe for cooperating with the metal ribs on the respective drum to break the excess plastic material from a respective lead.
Claim 6
Dependent Claim 30 words
An apparatus as defined in claim 3, wherein: the ribs on the drums and the ribs on the shoes are formed at an angle to the axis of the drum.
Claim 7
Dependent Claim 32 words
An apparatus as defined in claim 4, wherein: the metal ribs on the shoes extend into the space between the drums to break extending plastic portions from the bodies of the components.
