Patent number: 7600704Abstract: An absorbent product manufacturing apparatus including a pulp feed mechanism (2) for feeding a pulp sheet along a lower surface of a pulp guide part (2411) and a pulp crushing mechanism (3) for crushing the pulp sheet from the pulp feed mechanism (2). The pulp crushing mechanism (3) crushes the pulp sheet with a first crushing cylinder (312) and a second crushing cylinder (322). The crushing cylinders are disposed so as to be inclined with respect to a direction of feeding the pulp sheet. This reduces the force necessary to draw the pulp sheet in the feeding direction and suppresses an increase in the movement speed of the pulp sheet in crushing a rear end portion of the pulp sheet. As a result, it is possible to increase the amount of crushed pulp to be generated in a unit time and to maintain uniformity in the quality thereof.Type: GrantFiled: August 10, 2005Date of Patent: October 13, 2009Assignee: Livedo CorporationInventor: Kazuya Maruhata

Patent number: 5249751Abstract: A flailer for cutting forage-type materials in a feed reel mixer or similar machine has a powered shaft with a plurality of flailing blades swingably mounted in a full helix fashion, and an arcuate hood for directing material into the path of the flailing blades and containing the resulting debris. An intake shield having a resilient flap attached thereto is mounted to the hood at its inlet to prevent undesirably large materials from entering the flailer. Another resilient flap at the outlet side of the hood directs cut materials down onto the auger and helps contain the dust from flailing. A second set of stationary blades mounted on the inside of the hood near its inlet cooperates with corresponding flailing blades to shear the materials in a series of smooth individual cuts, conserving power and reducing vibration.Type: GrantFiled: September 21, 1992Date of Patent: October 5, 1993Assignee: Schuler Manufacturing & Equipment Co., Inc.Inventor: Dorland H.

Patent number: 5213274Abstract: A feeding mechanism is for feeding cylindrical containers having a diameter and a major length dimension to a cutting machine and includes a pair of parallel feed shafts centrally disposed above the cutting machine. The feed shafts have parallel axes of rotation for rotation in opposite directions. The feed shafts have a predetermined distance therebetween to provide a predetermined gap between the feed shafts which is greater than the diameter of the cylindrical container. Each of the feed shafts includes a pair of feed discs mounted for rotation therewith. The pair of feed discs on each shaft include corresponding curved sectors which cooperate with corresponding curved sectors of the pair of feed discs on the other shaft for gripping the sides of the container therebetween. Rotation of the shafts toward the cutting machine causes the container entrapped by the corresponding curved sectors to be fed in an end first direction toward the cutting machine.Type: GrantFiled: May 4, 1992Date of Patent: May 25, 1993Assignee: Allegheny Paper Shredders, Inc.Inventor: Frank J.

Patent number: 5088532Abstract: A method and mechanism for controlling the material feed of a machine for chipping wood or brush. The machine has a pair of coacting feed rolls which feed material to be chipped into a rotating chipper that is driven by an engine of variable speed. Hydraulic motors for driving each of the feed rolls are actuated when the speed of the engine is at least a selected high level appropriate for efficient chipping. If the material is of a size or composition to load the engine below a selected low level adverse to efficient chipping, the hydraulic motors are interrupted to stop feeding of the material to allow the engine to return to an efficient chipping speed. When the engine has recovered to at least the selected high level, the hydraulic motors are reactivated to again feed material into the chipper.Type: GrantFiled: June 5, 1990Date of Patent: February 18, 1992Assignee: Vermeer Manufacturing CompanyInventors: Thomas A. Eggers, Alan J. Yoder
