Corrugated Pipe Technology

I read with a chuckle this add that Corma sent around the world today in an email blast. I was surprised to see Corma claiming “The first perforator ever to accomodate in-line couplings”.

Corma HSC series 2 perforator

I first became aware of the Valley Gear slotting perforator in the late 90’s which had a slotter spindle retraction system allowing an in-line coupler to pass by the cutting heads without the bell itself being perforated.

I am aware Valley Gear have a number of US patents on their perforators that deal with many of the mechanics that would be similar to the design Corma are promoting to have invented.

You can view these patents for yourself by going to any of the numerous patent search sites and looking up any of the following patents.

 If you are looking at the Corma HSC Series 2 perforator ask the hard questions of Corma about the state of existing patents governing the design. As a buyer I would definetly want their guarantee that the design is free from infringing other patents, and I would ask them to indemnify me from harm if as a user I was drawn into patent litigation.

If you find this topic interesting, or better still have some comments about the subject please take the time to add a comment and I’ll get it on the blog in quick time.

Beware on this design.
