Abstract: A die grooving tool for insertion into a pipe having a first die body and a second die body mounted upon a first end of the first die body. Each of the first die body and a second die body have a plurality of openings thereon for receiving a plurality of cutting wheels mounted therein. The first die body is configured to rotate at least partially in a clockwise direction and the second die body is configured to rotate at least partially in a counter clockwise direction, so that the cutting wheels of the first die body and the second die body create a double helix groove on an interior of the pipe, whereby the double helix groove intersects at an intersection point every 360 degrees along an entire length of the pipe.

Abstract: A guide roller for centering conveyor belts for a conveyor assembly. The roller has a securing end for attachment to the conveyor assembly and a substantially cylindrical body adapted to receive a conveyor belt thereon and having a first end, a second end and an undercut portion positioned substantially between the first end and the second end, which is adapted to receive and secure therein a belt edge of a conveyor belt. The first end and second have a greater diameter than that of the undercut portion, so that the belt edge of the belt is secured without lateral movement of the belt.
