Abstract: A system for adapting existing conventional screw machines to be capable of computer numerical control operation. The system incorporates the use of a VersaCam device which replaces the turret cam of a single spindle screw machine. The VersaCam system monitors the motion of the screw machine camshaft and actuates the turret slide in synchronization with the camshaft. The VersaCam system also provides a means of specifying the desired turret slide trajectory for any given job.

Abstract: A linear guide assembly which includes a slide body that is moveably supported on a guide rail by a non-rolling bearing insert. A channel extends longitudinally through the body and the guide rail is received in the channel. The bearing insert facilitates longitudinal movement of the body along the rail. The nature of the mounting of the bearing insert to the body in the channel is such that the bearing insert can be readily removed from the body when excessively worn and replaced without also requiring replacement of the body.

Abstract: A continuous motion sealer of a type typically employed for applying metallic foil seals to the mouths of containers for fluid comestibles is disclosed. The device includes means for cutting a flat seal of predetermined profile from a roll-supplied heat activated material, and transport the seal to the containers or other parts following which it is heat sealed. Improved camming means is provided which enables the sealing heater to engage a seal in the absence of other than vertical motion. A punch and die assembly includes a programmable electronic material advance mechanism. Each sealing head assembly includes an electronic band heater and thermocouple, as well as a vacuum pickup for individual seals. The thermocouple communicates with a separate sealing head temperature controller, programmable with regard to temperature setting, and an alarm connected to a system shutdown in the event of failure.
