Method for producing and handling elongated tubular items

Claim 1

A METHOD OF PRODUCING DRAIN TILE COMPRISING, (A) MOVING A ROTARY CUTTER WITH A CONTINUOUS MOVING TUBULAR EXTRUSION OF CLAY MATERIAL AND AS A UNIT AND DURING SUCH MOVEMENT, (B) ROTATING THE CUTTER ABOUT ITS AXIAL CENTER OF ROTATION WHICH EXTENDS IN THE SAME DIRECTION IS THE LENGTHWISE AXIS OF SAID CONTINUOUS TUBULAR EXTRUSION TO SEVER A PREDETERMINED LENGTH OF CLAY MATERIAL FROM SAID CONTINUOUS EXTRUSION, (C) PROVIDING AT LEAST THREE POWER DRIVEN ROTATABLE ROUNDER ROLLS WHEREIN THE AXES OF ROTATION OF SAID ROLLS ARE DISPOSED IN PARALLEL TO THE AXIS OF SAID PREDETERMINED LENGTH OF MATERIAL, (D) ROUNDING SAID PREDETERMINED LENGTH OF MATERIAL INTO SYMMERICAL FORM BY ENGAGING IN SUPPORTING RELATION SAID PREDETERMINED LENGTH WITH SAID ROLLS AT THREE CIRCUMFERENTIALLY SPACED LOCATIONS ON SAID PREDETERMINED LENGTHS PERIMETER AND ROTATING SAID ROLLS TO CAUSE ROTATION OF SAID PREDERMINED LENGTH A GENERALLY HORIZONTAL CONDITION ABOUT ITS LENGTHWISE AXIS WHILE MAINTAINING THE LAST MENTIONED AXIS SUBSTANTIALLY STATIONARY AGAINST SIDEWISE MOVEMENT DURING SAID ROUNDING, (E) CUTTING SAID PREDETERMINED LENGTH INTO A PLURALITY OF SHORTER LENGHT SECTIONS, AND (F) STACKING SAID SHORTER LENGTH SECTIONS IS SUPERIMPOSED CONDITION ON A RECEIVING PLAFORM.

Claim 2

A METHOD OF PRODUCING DRAIN TILE COMPRISING, (A) MOVING A ROTARY CUTTER WITH A CONTINUOUS MOVING TUBULAR EXTRUSION OF CLAY MATERIAL AND AS A UNIT AND DURING SUCH MOVEMENT, (B) ROTATING THE CUTTER ABOUT ITS AXIAL CENTER OF ROTATION WHICH EXTENDS IN THE SAME DIRECTION IS THE LENGTHWISE AXIS OF SAID CONTINUOUS TUBULAR EXTRUSION TO SEVER A PREDETERMINED LENGTH OF CLAY MATERIAL FROM SAID CONTINUOUS EXTRUSION, (C) PROVIDING AT LEAST THREE POWER DRIVEN ROTATABLE ROUNDER ROLLS WHEREIN THE AXES OF ROTATION OF SAID ROLLS ARE DISPOSED IN PARALLEL TO THE AXIS OF SAID PREDETERMINED LENGTH OF MATERIAL, (D) ROUNDING SAID PREDETERMINED LENGTH OF MATERIAL INTO SYMMERICAL FORM BY ENGAGING IN SUPPORTING RELATION SAID PREDETERMINED LENGTH WITH SAID ROLLS AT THREE CIRCUMFERENTIALLY SPACED LOCATIONS ON SAID PREDETERMINED LENGTHS PERIMETER AND ROTATING SAID ROLLS TO CAUSE ROTATION OF SAID PREDERMINED LENGTH A GENERALLY HORIZONTAL CONDITION ABOUT ITS LENGTHWISE AXIS WHILE MAINTAINING THE LAST MENTIONED AXIS SUBSTANTIALLY STATIONARY AGAINST SIDEWISE MOVEMENT DURING SAID ROUNDING, (E) CUTTING SAID PREDETERMINED LENGTH INTO A PLURALITY OF SHORTER LENGHT SECTIONS, AND (F) STACKING SAID SHORTER LENGTH SECTIONS IS SUPERIMPOSED CONDITION ON A RECEIVING PLAFORM.
