Photo 004, 005, 006: Are of a 15" diameter clockwise custom straight parallel screw feeder. This bowl was designed to feed head heavy blanks. These are blanks where the head is larger than the body, causing parts to want to stand on their heads. This feeder has a 1/2 tube section at the breakout that lays the part down and allows it to hang in the rails at a high feed rate. This bowl was built for a small EW Menns threader. Feed rates were consistant at over 500 PPM.
Photo 007, 008: Are of a 18" counter clockwise custom tooled feeder bowl made to feed brass eyelets into an assembly machine. Parts had to feed eyelets leading down a drop tube. Parts were for a hook and eye assembly.
Photo 009, 010: are of a 21" diameter counter clockwise airless screw feeder. We were feeding a #8 x .625 headed blank at 600 plus PPM without the use of any air. Note the open area where parts hang on the edge of the rail. This area allows unorientated parts to clean without the use of air. This was a high volume part and the customer wanted a dedicated bowl.
