Abstract

A machine for distributing blowing wool from a bag of compressed blowing wool is provided. The machine includes a chute having an inlet end. The inlet end is configured to receive the bag of compressed blowing wool. A shredding chamber is positioned downstream from the chute and is configured to shred and pick apart the blowing wool. The shredding chamber includes a plurality of shredders configured for rotation. The shredding chamber further includes a plurality of guide shells positioned partially around the plurality of shredders. The plurality of shredders seal against the plurality of guide shells and direct the blowing wool in a downstream direction as the plurality of shredders rotate.

Claims (10)

1. A machine for distributing blowing wool from a bag of compressed blowing wool, the machine comprising:

a chute having an inlet end, the inlet end configured to receive the bag of compressed blowing wool; and

a shredding chamber positioned downstream from the chute and configured to shred and pick apart the blowing wool, the shredding chamber including a plurality of shredders configured for rotation, wherein the plurality of shredders includes at least one low speed shredder and at least one agitator, the shredding chamber further including a plurality of guide shells positioned partially around the plurality of shredders, wherein the at least one low speed shredder has a guide shell that is curved and extends to form an arc of approximately 90° and the at least one agitator has a guide shell that is curved and extends to form an arc of approximately 180°;

wherein the plurality of shredders seal against the plurality of guide shells and direct the blowing wool in a downstream direction as the plurality of shredders rotate.

2. The machine of claim 1 , wherein the at least one agitator is configured to rotate at a higher speed than the at least one low speed shredder.

3. The machine of claim 1 , wherein the at least one low speed shredder and the at least one agitator are configured to rotate in the same direction.

4. The machine of claim 3 , wherein the at least one low speed shredder and the at least one agitator are configured to rotate in a counter-clockwise direction.

5. The machine of claim 1 , wherein the at least one low speed shredder includes a plurality of paddle assemblies mounted to a shredder shaft, each paddle assembly including a plurality of paddles, wherein the paddles form an angle greater than 0° relative to an axis that is perpendicular to the shredder shaft.

6. The machine of claim 5 , wherein the paddles are mounted at an angle in a range of from about 40° to about 50°.

7. The machine of claim 6 , wherein the paddles are all mounted at the same angle relative to the shredder shaft.
