摘要： A standpipe is connected into a fiber processing system such as a pressurized stock line of a paper making system, containing refined stock, or unrefined pulp, at operating consistencies. Automatic controls cycle a measurement chamber, in the standpipe, through intake measure and exhaust. An imperforate plate mounted across the measurement chamber has at least one hole of predetermined cross dimension, or diameter, substantially equal to the relative length of fiber desired. Automatic timing establishes a set intake time for slurry, or suspension, to pass through the hole and contact lower and/or upper liquid level sensors, or other level indicators, in the chamber. Instantaneous, periodic read out is provided to indicate "too short", "too long" or "correct length" with each cycle. Differential pressure, across the hole, or orifice during measure, as well as approach velocity, is appropriately controlled.

摘要： A vortical circulation pulper, of the type designed to pulp difficult to defiber stock, and having a rotor revolving within a stator, in one wall of a pulp container, to circulate a charge in a path within the container, a rotor/stator, stock reduction, interface alongside the path for reducing the size of chunks to smaller pieces and a rotor/stator stock attrition interface in rear of said stock reduction interface on the path to receive and defiber said smaller pieces is provided with a bidirectional rotor and a bidirectional stator, both having symmetrical, generally, isosceles triangle shaped peaks and valleys therearound. Rotation of the rotor can thus be reversed when its stock reduction edges wear down and such reverse rotation, resharpens the worn edges.

摘要： A vortical circulation type pulper has a bladed and channelled rotor and an annular bladed and channeled stator mounted in a side, or bottom, wall, the rotor and annular stator forming a truncated conical attrition interface with the small end receiving stock for passage through the interface to the large end and thence for discharge or recirculation. Rotor/stator clearance at rest, is about 15/1000 of an inch. The stator is provided with an annular, pattern of alternate, triangular acquisition valleys and bladed and channeled peaks, each peak having an acquisition edge in the path of the stock reduction, edges of the rotor vanes so that the stock is reduced by the scissors-like contact of stock reduction edges of the vanes with the acquisition edges of the stator peaks in a stock reduction interface until sufficiently defibered to enter the truncated conical, bladed and channeled rotor/stator attrition interface for further treatment and recirculation or discharge.

摘要： An extrusion coater for high viscosity, thin coatings of the hot melt type, includes an elongated slot coating head across which the web to be coated is advanced under tension and includes a lead-on lip at the slot plus a fixed, unyieldable, lead-off lip having an elongated, rotatable, cylindrical rod deeply seated for about two thirds of its circumference therein and unyieldably supported on a fixed axis of rotation. A yieldably mounted, press roll with a rubber like surface forms a pressure nip with the smooth hard unyieldable surface of the rod and the rod is rotated intermittently, or continuously by power means depending on the amount of impurities in the coating media. The rod rotation is not for metering purposes but for spreading wear while overcoming any streaking.

摘要： The horizontal platform between the feed roll nip and the rotary cutter pelletizing nip in a dicer is arranged to feed soft, limp webs of plastic without crumpling, buckling or sidewise movement by providing a multiplicity of closely spaced ribs and grooves on both the platform and on the hold down fingers, extending in the direction of feed. Friction is thus reduced in the feed direction while sidewise control is maximum for a given feed resistance. To prevent the soft plastic from wrapping around the lower feed roll it is formed with a multiplicity of small diamond protuberances separated by channels.

摘要： A screen changer mounted between a flowable plastic extruder and a die has a clamp frame movable rectilinearly across the extrusion passage by fluid piston and cylinder means to successively position one of four screen blocks across the passage. A used block is removable from the frame at one end, whereupon latch mechanism retains three blocks while the frame retracts to receive a fresh block. Each block contains a filter recess, a purge recess and a pre-fill groove in the upstream face, so that the incoming block is pre-filled with plastic and purged while moving into position across the passage.

摘要： For supplying high viscosity coating material in liquid form to a coating machine from drums of solid material, the opposite ends, or heads of each drum are removed and the drums are successively inserted between a vertically, upstanding heated, stationary, lower mandrel, and a vertically, downwardly movable upper platen of a press. As the upper platen presses the open ended drum down the heated lower platen liquifies the coating to pass therethrough to a holding tank. The lower platen, or heat exchanger includes a tapered, truncated conical, sharp edged outer area, radial fins and a central, conical inner area for contacting the material.

摘要： A vortical circulation type pulper has a bladed rotor and stator with a fixed clearance and operates at conventional horsepower to defibre conventional pulp, capable of being defibered, until the fibres are separated. With unconventional pulp, hemp, flax, rags, leather, and certain rejects, which cannot be so defibered, the rotor of the pulper of this invention is advanced to zero clearance and the horsepower increased about fifty percent, the resultant thrust grinding the mass of pulp, and then fibrillating the fibres in the pulper to a desired degree of refining. The rotor then backs off and the refined pulp is dumped from the pulper. An automatic freeness tester senses the condition of the pulp and actuates the electric control circuit.

摘要： A die, preferably one with internal metering pumps for applying an extremely uniform coating to a traveling web, is mounted over a pair of very rigid side plates. Horizontal surfaces of the plates support linear slides which in turn support the die through uprights. The slides have preloaded bearings to allow a linear movement of each upright with no lost motion. Pneumatic cylinders move each upright along its slide independently of the other upright. Adjustable stops set the die-to-web spacing when the cylinders draw the uprights, and therefore the die, toward the web. Other air/hydraulic cylinders drive the uprights away from the web, against the action of the main cylinders, to jump splices in the web. The system preferably includes an outrigger arm extending from each upright to a pair of auxiliary linear slides mounted on the side face of each side plate to relieve side loading on the main linear slides. In the preferred form, the stops are positioned and the actuators are controlled by a servo loop to provide, in combination with the independently movable uprights, continuous automatic control of the cross web coating dimensions in response to a coating thickness sensor. The servo system preferably also controls adjustment screws across the die to provide a continuous automatic control of the web coating profile.
