WIRE STOAIGHTENING AND M()M)1.\(; F<»K HKLAVS

The last operation performed by the die is that of sheaiiiig the wire 

 ill th(^ molded assembly to form iiidixidual combs. One set of opijosiiij;- 

 slieariiiii details for each lin(> of molded assemblies is adjustably mounted 

 on the base phiti> of the lower die half, Fig. 17. When the die is closed, 

 the upper details butt against the upper (he plate thereby forcing the 

 cutting shears upon the wire. To reduce the forc(> lecjuired, the cutting 

 blades are so tapered that they cut each wire in succession. 



Upon termination of the cutting operation, the parts fall free (jf the 

 guide rails into chutes leading to the fiont of the pre.ss, thus comjjleting 

 the molding operation. 



CONCLUSION 



The original objective of embedding a multiplicity of straightened 

 small diameter wires in phenolic resin blocks (Fig. 18) on a commercial 

 basis has been accomplished. These wire spring relay parts are being pro- 

 duced at low cost to the required dimensional accuracy in automatic 

 molding machines.
