Method and apparatus for partitioning and shaping a fibrous batt

Apparatus for shaping a web of fibers comprising:

• a pair of rolls disposed adjacent each other with their axes parallel, said rolls each having at least one jaw member affixed to the roll and extending about a portion of the periphery of the roll, each jaw member comprising a non-resilient means and a resilient means disposed adjacent each other, said non-resilient means being constructed with a furthest tip of said means projecting outwardly from the surface of the roll at least about 0.1 inch;
• the non-resilient means having a first face forming said furthest tip, said first face disposed perpendicular to a plane in which the axis of the roll lies, a second face forming an angle of 90.degree. or less with said first face at oned end thereof and extending from said end at least to the surface of the roll, and a third face extending from the opposite end of said first face to the surface of the roll;
• the resilient means disposed adjacent the second face of the non-resilient means, said resilient means having a first face disposed perpendicular to a plane in which the axis of the roll lies, a second face forming an angle of about 90.degree. or less with said first face at one end thereof and extending from said end to the surface of the roll, and a third face extending from the opposite end of said first face to the surface of the roll, said resilient means projecting outwardly from the surface of the roll at least about as far as said non-resilient means and extending along the surface of the roll at least as far as said non-resilient means, and means for rotating the rolls in opposite directions so that jaw members on the oppositely rotating rolls engage each other in a manner that the non-resilient means of one roll engages the oppositely rotating resilient means of the other roll with the second face of the non-resilient means of one roll passing the second face of the non-resilient means of the other roll with a clearance between the faces of at least 0.03 inch.

Apparatus for shaping a batt of loosely compacted short fibers comprising:

• a pair of rolls disposed adjacent each other with their axes parallel, said rolls each having at least one jaw member affixed to the roll and extending about a portion of the periphery of the roll, each jaw member comprising a non-resilient means and a resilient means disposed adjacent each other, said non-resilient means being constructed with a furthest tip of said means projecting outwardly from the surface of the roll at least about 0.1 inch;
• the non-resilient means having a first face forming said furthest tip, said first face disposed perpendicular to a plane in which the axis of the roll lies, a second face forming an angle of 90.degree. or less with said first face at one end thereof and extending from said end at least to the surface of the roll, and a third face extending from the opposite end of said first face to the surface of the roll;
• the resilient means disposed adjacent the second face of the non-resilient means, said resilient means having a first face disposed perpendicular to a plane in which the axis of the roll lies, a second face forming an angle of about 90.degree. or less with said first face at one end thereof and extending from said end to the surface of the roll, and a third face extending from the opposite end of said first face to the surface of the roll, said resilient means projecting outwardly from the surface of the roll at least about as far as said non-resilient means and extending along the surface of the roll at least as far as said non-resilient means, and means for rotating the rolls in opposite directions so that jaw members on the oppositely rotating rolls engage each other in a manner that the non-resilient means of one roll engages the oppositely rotating resilient means of the other roll with the second face of the non-resilient means of one roll passing the second face of the non-resilient means of the other roll with a clearance between the faces of at least 0.03 inch.

Apparatus for partitioning a batt of loosely compacted short fibers comprising:

• a pair of rolls disposed adjacent each other with their axes parallel, said rolls each having at least one jaw member affixed to the roll and extending along the surface of the roll parallel to the roll axis a distance at least equal to the width of the batt being partitioned;
• each jaw member comprising a non-resilient means and a resilient means disposed adjacent each other, said non-resilient means being constructed with the furthest tip of said means projecting outwardly from the surface of the roll at least about 0.1 inch;
• the non-resilient means having a first face forming said furthest tip, said first face disposed perpendicular to a plane in which the axis of the roll lies, a second face forming an angle of 90.degree. or less with said first face at one end thereof an extending from said end at least to the surface of the roll, and a third face extending from the opposite end of said first face to the surface of the roll;
• the resilient means disposed adjacent the second face of the non-resilient means, said resilient means having a first face disposed perpendicular to a plane in which the axis of the roll lies;
• a second face forming an angle of about 90.degree. with said first face at one end thereof and extending from said end to the surface of the roll, and a third face extending from the opposite end of said first face to the surface of the roll, said resilient means projecting outwardly from the surface of the roll at least about as far as said non-resilient means and extending along the surface of the roll parallel to the roll axis at least as far as said non-resilient means, and means for rotating the rolls in opposite directions so that jaw members on the oppositely rotating rolls engage each other in a manner that the non-resilient means of one roll engages the oppositely rotating resilient means of the other roll with the second face of the non-resilient means of one roll passing the second face of the non-resilient means of the other roll with a clearance between the faces of at least 0.03 inch.
