The extrusion head used in blow molding is one of three basic styles : the spider or axial flow head, the side feed or radial flow head, and the accumulator head. In the simplest form of the spider or axial flow head, a central torpedo is positioned in the melt flow path supported generally by two spider legs. The smooth and direct path with little or no place for material to hang up and degrade makes this head ideal for PVC resin. Cross-sectional areas of the melt flow path from the extruder, over the torpedo, and over the spider legs are carefully balanced to ensure an even and consistent pressure and flow.

The extrusion head used in blow molding is one of three basic styles : the spider or axial flow head, the side feed or radial flow head, and the accumulator head.... The side feed or radial flow head is a design most often used for polyethylene. Melt enters the head from the side, divides around the mandrel, and rewelds. As the melt moves downward, it enters the pressure ring area, creating a tremendous back pressure that helps ensure the resin reweld. The head is used for its simplicity and ruggedness, but has the disadvantage of relatively long color changes.

DEF

A heavy, crawler-tracked, 200-horsepower cutter loader designed for longwall faces in seams over 4½ feed thick, and takes a buttock 5 feet wide. The maximum cutting head is 7½ feet.... The cutterhead consists of seven cutter chains mounted side by side and can be moved up and down radially to cut the coal from roof to floor. It delivers the coal onto the face conveyor by a short cross conveyor. Capacity is over 400 tons per machine and over 4 tons output per man per shift.
