​Roll Thread Turnaround Sleeves

​In some special threading applications, you may have the need to thread a part that will not feed into a rail system from a vibratory feeder, unless you hand feed them. We have designed and made many turn around systems that can eliminate hand feeding of these type of parts.

Our solution: The part will be fed normally thru the vibrator feed bowl and half way down the rail system the part will go thru a 180 degree turn around that will invert the part, re-install it on the rail and thread the part that would normally have to be hand fed.

We can either manufacture a turnaround that you have designed or you can send us samples of the parts and we can design a turnaround to work for your specific needs. Including aftermarket turnarounds that fit Chun Zu, Hartford, Waterbury, EW Menn, Sanmei, Saspi, Manville, Landis and more.

Complete Rail Assemblies & Accessories

Our roll thread rail assemblies can be ordered complete and  ready to go, in standard or long length, and we install all of the needed accessories for you so you don't have to deal with the hassle. But if you are just looking for that one or two missing or broken pieces we also sell all accessories separate (see below for list of accessories).
