Cutting apparatus

Apparatus for cutting record members from a longitudinally extending web, the apparatus comprising:

• a stationary frame, a cutting mechanism including a generally annular rotatable knife, an elongate knife cooperable with the rotatable knife at a chord of the rotatable knife, means for mounting the cutting mechanism on the frame for movement as a unit with a longitudinally traveling web, means for moving the rotatable knife for travel in a direction generally parallel to the elongate knife to sever a generally rectangular record member rom the web while the cutting mechanism and the web are traveling as a unit, wherein the traveling web moves the cutting mechanism longitudinally in the direction of web travel by engagement of the knives with the web, means for accelerating movement of the cutting mechanism in the direction of web travel before the knives begin to sever the web, wherein the cutting mechanism includes a pair of relatively movable mounting members, wherein the elongate knife is mounted on one of the mounting members and the rotatable knife is mounted on the other mounting member, and means for biasing one of the mounting members to urge the rotatable knife and the elongate knife into cooperating cutting relationship.
