Laich Plastics was an injection molder who molded the helmets for Sport Products.

When sport products was in financial  trouble Laich took it over.

 

I was instrumental in replacing [the] foam strips in the original helmets with an adjustable plastic liner.

 

Sport Products filed a patent for [the Adjustrap] and received [it], only to be overturned.

The Seventy Corporation, headed up by myself, produced millions of helmets for helmet days

in both major and minor leagues from 1969 thru 1976.
