An improved stuffer box crimping apparatus of the type in which tow is fed into a rectangular cross-section crimping chamber off-set from the bite of a pair of feed rolls, the apparatus employing a crimping chamber wherein one wall is predominantly formed by a single doctor blade and an opposite wall is formed by a portion of the rotating surface of one of the cylindrical feed rolls of the feed roll pair, the doctor blade being pivotally mounted on the feed roll nearest the tip portion of the doctor blade. The cross-sectional area of the crimping chamber diminishes toward the exit portion thereof, whereby crimped filamentary material within the crimping chamber is subjected to both back pressure and a constant forwarding action by the rotating surface of the cylindrical feed roll. The pivotal mounting of the doctor blade provides precise clearance and allows the volume of the crimping chamber to adjust in accordance with tow variations.

A console unit, particularly for use by a dental assistant, adapted to carry powered handpiece instruments and to provide storage space and working space utilized during the treating of a patient, is characterized by a mobile construction for easy access thereto. A main cabinet portion is provided for containing support apparatus for the powered handpiece instruments and for providing storage space. An upper work surface portion is movably carried by the main cabinet portion and has an upper generally flat working surface area thereon. A powered handpiece instrument storage compartment is secured to and suspended from one side of the upper work surface portion for movement therewith and for removably carrying a plurality of powered handpiece instruments and attached operating flexible hose for easy removal and use. Devices mount the upper work surface area for horizontal, forward and return movement for positioning of the upper work surface area and the handpiece instrument storage compartment in desired proximity to a user positioned in front of the console unit. Devices mount the upper work surface portion on the main cabinet portion for vertical upward and return movement of the upper work surface portion and the handpiece instrument storage compartment for positioning thereof at a desired elevation for easy access by the user.
