Abstract
In a method of handling a tubular carton blank, one side of an erected tubular carton blank is gripped with a gripper mounted to a pivot such that a fold line of a flap of the one side is aligned with an axis of rotation of the pivot. The gripper, and thereby the erected tubular carton blank, is then pivoted about the pivot. The flap is brought into abutting relation with an abutment during the pivoting so that the flap is progressively folded about the fold line by the abutment during the pivoting.
Claims17
A method of handling a tubular carton blank, comprising:
- gripping one side of an erected tubular carton blank with a gripper mounted to a pivot such that a fold line of a flap of said one side is aligned with an axis of rotation of said pivot;
- pivoting said gripper, and thereby said erected tubular carton blank, about said pivot;
- bringing said flap into abutting relation with an abutment during said pivoting so that said flap is progressively folded about said fold line by said abutment during said pivoting.
Apparatus for handling a tubular carton blank comprising:
- a pivot arm rotatable in a rotational path about a pivot at a base of said pivot arm from a first position to a second position;
- a gripper supported by said pivot arm;
- a stationary abutment in said rotational path beyond said second position, said stationary abutment at an opposite side of said pivot to said pivot arm when said pivot arm is in said first position.
