Abstract:
A machine for cutting rods from rod stock, the machine comprising:means for advancing the rod stock along a first axis; a closed knife mounted for reciprocating movement through said axis between first and second positions, said knife having an opening (i) extending along said axis and through which the advancing rod stock passes when the knife is in said first position and (ii) radially displaced from said axis when in said second position, said knife further having an edge to shear off a rod from the rod stock upon moving toward said second position; an air supply having a discharge port (i) positioned upstream of the knife, and (ii) in fluid communication with said opening and oriented to discharge through said opening when said knife is in said second position for ejecting the cut rod from the knife; and further comprising a (a) gage surface (i) located downstream of said knife, (ii) facing towards said knife, and (iii) intersecting said axis to position the advancing rod stock in the knife, and (b) a contact surface (i) in fixed relation with said gage surface, (ii) extending in a direction away from said gage surface, and (iii) facing towards said second position with respect to said axis to engage a sheared rod that may be carried back in the knife as it returns to said first position, said gage surface and contact surface being connected for resilient movement away from and towards said axis as the knife returns to said first position to enable discharge of said sheared rod from the knife in said first position by the advancing stock.
