Abstract
Abstract A rotary knife for use as a label cutter in an article addressing machine. The rotary knife comprises a hub member supported for rotation and having attached thereto a blade holder for removably receiving a cutting blade. The blade holder is secured to the hub in a contilevered fashion by means of a plurality of bellville washers whereby parallelism between the blade and an anvil with which the rotary knife cooperates to both feed and cut label strip material is maintained.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
185 words
Rotary feeding and cutting apparatus comprising: an anvil supported for rotation; a hub member having means cooperating with said anvil for feeding paper through a nip formed therebetween, said hub member being supported for rotation adjacent said anvil; a cutting member including an edge extending in a radial direction beyond said cooperating means; and, means for mounting said cutting member to thereby maintain parallelism at all times between an edge of said cutting member and said anvil when in contact with said paper, the mounting means including: a holder for said cutting member, the holder being mounted for pivotal movement substantially about the axis of rotation of said hub member and along said axis of rotation, and fastening means including a plurality of bellville washers; a first screw, passing through the plurality of washers, for securing one end of said holder to said hub member; another bellville washer; a second screw, passing through said another bellville washer, for securing the other end of said holder to said hub member, said screws being disposed on opposite sides of the axis of rotation of said hub member.
Claim 2
Dependent Claim
185 words
Rotary feeding and cutting apparatus comprising: an anvil supported for rotation; a hub member having means cooperating with said anvil for feeding paper through a nip formed therebetween, said hub member being supported for rotation adjacent said anvil; a cutting member including an edge extending in a radial direction beyond said cooperating means; and, means for mounting said cutting member to thereby maintain parallelism at all times between an edge of said cutting member and said anvil when in contact with said paper, the mounting means including: a holder for said cutting member, the holder being mounted for pivotal movement substantially about the axis of rotation of said hub member and along said axis of rotation, and fastening means including a plurality of bellville washers; a first screw, passing through the plurality of washers, for securing one end of said holder to said hub member; another bellville washer; a second screw, passing through said another bellville washer, for securing the other end of said holder to said hub member, said screws being disposed on opposite sides of the axis of rotation of said hub member.
Claim 3
Dependent Claim
51 words
Apparatus according to claim 1 wherein said holder includes a leg portion contacting a surface of said hub member and said of bellville washers are stacked in engagement with an end of said holder remote from said leg portion and the surface of said hub member contacted by said leg portion.
Claim 4
Dependent Claim
40 words
means for pivotally mounting the holder with the leg portion contacting a surface of the hub member to permit pivotal movement of the holder substantially about the axis of rotation of the hub member and along the axis of rotation;
Claim 5
Dependent Claim
40 words
means for pivotally mounting the holder with the leg portion contacting a surface of the hub member to permit pivotal movement of the holder substantially about the axis of rotation of the hub member and along the axis of rotation;
Claim 6
Dependent Claim
86 words
the means for pivotally mounting the holder comprising fastening means including a series stack of bellville washers for securing one end of the holder to the hub member, the stack engaging an end of the holder remote from the leg portion and the surface of the hub member contacted by the leg portion, and a single bellville washer for securing the other end of the holder to the hub member, said securing being accomplished on opposite sides of the axis of rotation of the hub member.
Claim 7
Dependent Claim
86 words
the means for pivotally mounting the holder comprising fastening means including a series stack of bellville washers for securing one end of the holder to the hub member, the stack engaging an end of the holder remote from the leg portion and the surface of the hub member contacted by the leg portion, and a single bellville washer for securing the other end of the holder to the hub member, said securing being accomplished on opposite sides of the axis of rotation of the hub member.
Claim 8
Dependent Claim
92 words
A rotary feeding and cutting device, comprising: a. an anvil supported for rotation; b. a hub member having means cooperating with said anvil for feeding paper through a nip formed therebetween, the hub member being supported for rotation adjacent said anvil; c. a cutting member including an edge extending in a radial direction beyond said cooperating means, and d. means for mounting the cutting member to thereby maintain parallelism at all times between an edge of the cutting member and the anvil when in contact with the paper, the mounting means including:
