Abstract
A method of roll packing a variety of compressible materials is provided which prevents the rotatable mandrel about which the materials are rolled from radially collapsing. The method further provides for easy removal of the roll packed material without tearing or telescoping of the material. One embodiment of the present invention provides for wrapping a corrugated material around the rotatable mandrel prior to the compressible material being wrapped around the mandrel. In another embodiment, roll-packing material is laminated prior to being wound upon the mandrel before the compressible material is wrapped around the mandrel.
Claims19
A method of roll packing a compressible material in a roll, the method comprising the steps of:
- providing a mandrel having a rotational axis;
- forming a core around the mandrel by wrapping corrugated material around the mandrel and securing the corrugated material to itself;
- feeding a compressible material to the mandrel;
- rotating the mandrel to wind the compressible material onto the mandrel to form a roll of compressed material;
- and
- removing the roll of compressed material including the core from the mandrel.
A method of roll packing a compressible material in a roll, the method comprising the steps of:
- providing a mandrel having a rotational axis;
- wrapping roll packing material around the mandrel by rotating the mandrel;
- wrapping a sheet of stiffening material around the mandrel;
- securing the stiffening material to itself;
- feeding a compressible material to the mandrel;
- rotating the mandrel to wind the compressible material onto the mandrel to form a roll of compressed material;
- and
- removing the roll of compressed material from the mandrel.
A method of roll packing a compressible material in a roll, the method comprising the steps of:
- providing a mandrel having a rotational axis;
- securing roll packing material to the mandrel;
- rotating the mandrel to wind the roll packing material onto the mandrel;
- feeding corrugated material to the mandrel;
- rotating the mandrel to wind the corrugated material around the mandrel;
- securing the corrugated material to itself, the corrugated material being wrapped around the mandrel;
- feeding a compressible material to the mandrel;
- rotating the mandrel to wind the compressible material onto the mandrel to form a roll of compressed material outside the corrugated material;
- and
- removing the roll of compressed material from the mandrel.
A method of roll packing a compressible material in a roll, the method comprising the steps of:
- providing a mandrel having a rotational axis;
- feeding corrugated material to the mandrel;
- rotating the mandrel to wind the corrugated material around the mandrel;
- securing the corrugated material to itself, the corrugated material being wrapped around the mandrel;
- feeding a compressible material to the mandrel;
- rotating the mandrel to wind the compressible material onto the mandrel to form a roll of compressed material outside the corrugated material;
- and
- removing the roll of compressed material from the mandrel.
A method of roll packing a compressible material in a roll, the method comprising the steps of:
- providing a mandrel having a rotational axis;
- securing roll packing material to the mandrel;
- applying adhesive to the roll packing material as the mandrel is rotated, the adhesive being sandwiched between layers of roll packing material;
- stopping the application of adhesive to the roll packing material;
- allowing the adhesive to dry, thereby creating a laminated sleeve;
- feeding a compressible material to the mandrel;
- further rotating the mandrel to wind the compressible material and the roll packing material onto the laminated sleeve to form a roll of compressed material;
- stopping rotation of the mandrel;
- cutting the roll packing material;
- and
- removed the roll of compressed material including the laminated sleeve from the mandrel.
A method of roll packing a compressible material in a roll, the method comprising the steps of:
- providing a mandrel having a rotational axis;
- securing roll packing material to the mandrel;
- begin rotating the mandrel;
- feeding roll packing material to the mandrel as the mandrel is rotating, thereby wrapping the roll packing material around the mandrel;
- applying adhesive to the roll packing material before the roll packing material is wrapped around the mandrel;
- stopping the application of adhesive to the roll packing material;
- allowing the adhesive to dry to create a laminated sleeve
- feeding a compressible material to the mandrel;
- further rotating the mandrel to wind the compressible material onto the laminated sleeve along with the roll packing material to form a roll of compressed material;
- and
- removing the roll of compressed material including the laminated sleeve from the mandrel.
A method of roll packing a compressible material in a roll, the method comprising the steps of:
- providing a mandrel having a rotational axis and a plurality of cleats movable between an expanded position and a collapsed position;
- forming a core around the mandrel with the cleats in the expanded position;
- feeding a compressible material to the mandrel with the cleats in the expanded position;
- rotating the mandrel to wind the compressible material onto the core to form a roll of compressed material;
- moving the cleats of the mandrel to the collapsed position;
- and
- removing the roll of compressed material including the core from the mandrel.
