Systems, methods and apparatus for dispensing of paper products. A paper product dispenser comprising a housing comprising a product holding area configured to hold a roll; a rotating member configured to rotate, in a first direction, in response to rotation of the roll; a cutting surface in the housing; a cutting blade coupled to the rotating member and having a first position, and a second position in which the cutting blade is in contact with the cutting surface, wherein the rotating member is configured to (i) move the cutting blade from the first position to the second position during a first portion of a rotation cycle of the roll in the first direction and (ii) move the cutting blade from the second position to the first position during a second portion of the rotation cycle of the roll in the first direction.

A saw mill has a head having at least one saw. The head is configured to travel on a track longitudinally to make alternating cuts between laterally spaced apart first and second work pieces. After traveling forward longitudinally to make a first cut of the first work piece at least one of the heads in the saw move laterally to then cut the second work piece on the return longitudinal trip.

A transfer apparatus for a sheet material article trimmer includes a transfer element configured to grip the sheet material article and move the sheet material article in a transfer direction onto a side table of the sheet material article trimmer. A driver is provided, the driver being configured to move the transfer element at the same speed as the side table during period of time when the sheet material article is gripped by the transfer element and the side table is moving in the transfer direction.

A chopper for chopping fibers or fiber strands having a back up roll and a blade roll containing blades that work against a peripheral surface of the back up roll and a method of using is disclosed. The chopper has a number of improved features for reducing the frequency of long fibers or long fiber strands and fuzz from getting into the chopped product. The chopper can have one or any combination of the improvements. The improvements include a strand guide located at least two feet up stream of the chopper, a first starting roll for starting a new strand that runs on a fluid bearing that can be adjusted to control the RPM of the first starting roll, a mount for a roll that runs against the peripheral surface of said back up roll, a strand guide insert for reducing fuzz generation and for preventing fuzz from getting into the product, and a deflector plate for catching and deflecting chopped strands thrown off the back up roll into a chopped strand product chute.

An apparatus for cutting, including an anvil cylinder which may have a plurality of cut rubbers strips affixed around the anvil cylinder and a cut cylinder which is mounted for rotation about an eccentric axis. Two knife boxes may be mounted on the cut cylinder, each knife box having a knife and cheekwood for securing the knife to the cut cylinder. A paper tape guides the material to be cut between the cut cylinder and the anvil cylinder. When one knife box degrades, a knife sleeve on the cut cylinder can be indexed so that the other knife box takes the place of the degraded knife box. When a cut rubber strip degrades, the anvil cylinder can be indexed so that another cut rubber strip takes the place of the degraded cut rubber strap. Either of these functions can occur while the apparatus is still running. The anvil cylinder can also use a cut rubber sleeve.

A clipper for cutting wood or plywood veneer transversely and other similar continuous sheet materials is described which ensures that the sheet material is cut in alignment and the cut achieves a square edge on the material. The clipper includes at least a pair of guillotine knife blades, each blade extending transverse to the sheet material, each blade cutting against a single anvil cylinder rotating in synchronization with the sheet speed. Each blade is preferably mounted in an actuating assembly which includes a crankshaft and a connecting rod. The blade is journaled to the crank of the connecting rod at its lower portion. The upper end of the connecting rod is guided along a radial line with respect to the center line of the anvil. Upon turning the crankshaft, the blade advances simultaneously vertically and horizontally into contact with the veneer. The imparted motion is such that the blade always remains substantially perpendicular to the surface of the veneer being cut. Thus the cut achieves a square edge on the veneer. The apparatus also ensures that forward conveyance of the veneer is not disturbed by the knife or anvil. Thus, the veneer is cut in transverse alignment and it exits the clipper aligned and in register with the conveyors.

A cutting device has a pair of pivotally connected members having knives affixed to their free ends. The pair of members move substantially reciprocally with respect to a continuously moving strand of material, such as wire, to be cut by said pair of knives. One of the pair of members extends beyond their pivot point and is connected via a first crank shaft to a first crank gear, at the side opposite the side having the ends with the knives, relative to the pivot point of the pair of members. Each member is also pivotally connected to a guide member which is arranged substantially normal to the feed direction of the strand of material. At least one of the two guide members is pivotally connected via a second crank shaft to a second crank gear. Gear means are provided to assure that the first and second crank gears rotate at the same speed.
