An impact cutoff device for a progressive high speed cold former having a low mass rigid cutter carriage, a torsion spring for carriage return, and an articulated, oil lubricated and dampened carriage drive block on a pivoting drive lever serving to reduce impact induced vibration otherwise leading to fatigue failure and wear of the various cutter parts and consequent loss of cutoff accuracy and quality.

An input conveyor, output conveyor, and knife assembly with a blade between the input and output conveyors all reciprocate back and forth as a blade moves perpendicular to the conveyors to cut portioned sized of product, such as ground meat. The cut cycle allows the product feed to keep moving in a continuous manner on conveyors. For ground meat, this system can allow production rates of 150 pieces or more per minute per conveyor line and can improve the accuracy of portioning. The blade is actuated by a profiled cam set that pulls the blade down, and then returns it with a spring to an upper position. The knife assembly can accelerate just after cutting to reduce the potential for sticking to the cut product.

A cutting device includes a cutting blade, a receiving block, a motor, a cutting blade movement mechanism, and a receiving block movement mechanism. The cutting blade includes a blade portion. The receiving block includes a contact surface including a first contact surface and a second contact surface. The motor is configured to rotate in a forward direction and a reverse direction. The cutting blade movement mechanism supports the cutting blade and is configured to move the cutting blade between a separated position and a contact position in concert with a rotation of the motor when the motor rotates in a forward direction and when the motor rotates in a reverse direction. The receiving block movement mechanism is configured to move the receiving block from a first opposed position to a second opposed position in concert with the rotation of the motor.

A dispenser for sheet material may include a feed roller with an integrated cutting mechanism that is movable with the feed roller for at least partially cutting or perforating the sheet material during dispensing thereof.
