Mold charge delivery

Apparatus for placing mold charges into a cavity, which includes:

• a pair of hubs mounted for rotation around parallel axes,
• a link connected between said hubs at positions off-center to said parallel axes, and
• a blade connected to said link for traveling in an elliptical path past an extrusion orifice to cut mold charges from said orifice and place the charges into cavities passing in sequence beneath said blade
• wherein said blade includes a shank for extending into the cavity to place the mold charge into the bottom of the cavity.

Apparatus for placing mold charges into a cavity, which includes:

• a pair of hubs mounted for rotation around parallel axes,
• a link connected between said hubs at positions off-center to said parallel axes, wherein the link includes a first portion connected to a first one of the pair of hugs and a second portion connected to a second one of the pair of the hubs, and
• a blade connected to said link for traveling in an elliptical path past an extrusion orifice to cut mold charges from said orifice and place the charges into cavities passing in sequence beneath said blade,
• wherein the first portion is connected to its respective hub at a first distance from the axis of rotation of that hub and the second portion is connected to its respective hub at a second distance from the axis of that hub that is not the same as the first distance.

• a blade connected to said link for traveling in an elliptical path past an extrusion orifice to cut mold charges from said orifice and place the charges into cavities passing in sequence beneath said blade,
• wherein the blade is cup-shaped and has a generally open end that permits a mold charge to engage the cavity in which it is received to facilitate removal of the mold charge from the blade.
