Cutting Table Cutting Tool Assembly
A cutting tool assembly that includes a holder that supports a blade for use with cutting tables. At least one roller is attached to the holder and extends beyond a perimeter of the holder in a direction that is normal to an axis of rotation of the roller. The blade extends from the holder in a common direction with the roller and includes a cutting edge that is oriented in a direction that is generally normal to the axis of rotation of the roller. During a cutting process, the roller maintains the position of the material with respect to the sharpened edge of the blade.
1 . A cutting table cutting tool assembly comprising:
a body having a first end for being secured to a mandrel of a cutting table system and a second end opposite the first end;
a guide attached to the second end of the body and having a material facing surface directed away from the second end of the body;
a blade attached to the body and extending beyond the material facing surface of the guide; and
at least one roller attached to the guide and extending beyond the material facing surface of the guide in a direction aligned with blade.
2 . The assembly of claim 1 further comprising another roller attached to the guide so that the at least one roller and another roller flank opposite sides of the blade.
3 . The assembly of claim 2 wherein the at least one roller and another roller extend the same distance beyond the material facing surface of the guide.
4 . The assembly of claim 1 further comprising a fastener and support that secures the blade to the body.
5 . The assembly of claim 4 further comprising a cavity formed in the guide and shaped to slidably receive the fastener and the support therein.
6 . The assembly of claim 5 further comprising a groove formed in the guide and positioned to allow at least a portion of a cutting edge of the blade to pass therethrough when the support is positioned in the cavity.
7 . A cutting tool assembly for use with cutting table systems, the cutting tool assembly comprising:
a holder constructed to engage a cutting table system;
a shoe attached to the holder;
an opening formed through the shoe;
a knife attached to the holder and extending beyond the opening formed in the shoe;
a cutting edge formed along a portion of the knife that extends beyond the shoe; and
a first roller and a second roller attached to the shoe so as to generally flank the knife, each roller having an outer race that extends beyond the shoe proximate the cutting edge.
8 . The assembly of claim 7 wherein the cutting edge extends an operating distance beyond a perimeter of each outer race in a direction perpendicular to an axis of rotation of each outer race.
9 . The assembly of claim 8 wherein the knife is attached to the holder so that the cutting edge is tilted so that only a portion of the cutting edge extends beyond the shoe.
10 . The assembly of claim 7 wherein the cutting edge extends in a direction that is generally perpendicular to an axis of rotation of one of the first and second rollers.
11 . The assembly of claim 7 wherein each roller is attached to the shoe so as to rotate about a common axis.
12 . The assembly of claim 7 further comprising a post attached to the shoe and constructed to engage an inner race of each of the first and second rollers.
13 . The assembly of claim 12 further comprising a lip formed proximate an end of each post and constructed to prevent translation of a respective roller in a direction generally aligned with an axis of rotation of the respective roller.
14 . The assembly of claim 13 further comprising a fastener for securing each post to the shoe.
15 . A method of forming a cutter assembly for use with cutting table systems comprising:
forming a mount body to cooperate with a cutting table system;
attaching a knife blade to the mount body;
attaching a shoe to the mount body so that a tip of the knife blade extends beyond a bottom surface of the shoe; and
attaching at least one roller to the shoe so that a surface of the roller that contacts a material to be cut is located between the tip of the knife blade and the bottom surface of the shoe in a direction generally perpendicular relative to a cutting direction.
16 . The method of claim 15 wherein attaching the knife blade to the mount body includes providing a support that extends along a portion of the knife blade and on a side of the knife blade opposite the mount body.
17 . The method of claim 15 further comprising attaching another roller to a side of the shoe opposite the at least one roller.
18 . The method of claim 17 further comprising attaching each roller with a hub that passes through each respective roller.
19 . The method of claim 18 further comprising forming a lip on at least one end of each hub, each lip restricting motion of a respective roller relative to the shoe in a direction that crosses an axis of the knife blade.
20 . The method of claim 15 further comprising providing an index for positioning the relative to the mount body.
