Abstract: A baler baling chamber has a movable chamber part pivotally mounted at a fixed chamber part. Several conveying units convey the bale along a circumferential wall. The baler can be transferred into a bale ejecting mode by pivoting the movable chamber part away from the fixed chamber part. One conveying unit is mounted at the moveable chamber part and adjacent to the fixed chamber part. In a bale forming mode, the adjacent conveying unit engages into a receiving aperture in the fixed chamber part and conveys loose material into the bailing chamber. The adjacent conveying unit can be pivoted away from the fixed chamber part and out of the receiving aperture increasing the aperture for ejecting a bale out of the bale forming chamber as the adjacent conveying unit is pivoted out of the receiving aperture.

Abstract: A tube flanging method includes the steps of: disposing a tube such that an edge thereof is exposed to the outside of a forming mold while the tube is inserted into the forming mold; applying an external force to the exposed edge of the tube to expand the exposed edge of the tube; applying an external force to the expanded edge to bend the expanded edge toward an outer surface of the forming mold; and applying an external force to the bent edge to form a flange, the flange having a linearly integrated cross section and being perpendicular to the longitudinal direction of the tube. With this configuration, it is possible to bend the tube to form the flange at a uniform thickness.

The actual value is the roll rotation shaft angular speed to be fed back to the speed controller.

Abstract: An agricultural baler has a bale chamber for the compression of crop into bales with a floor, ceiling, and two walls. A plunger forces crop into the bale chamber. An actuator system presses the ceiling and walls of the bale chamber inward. At least one retractable friction block in the ceiling or walls is used to increase the compression and density of the crop. The friction blocks extend inwards as an increasing function of either decreased pressure being exerted against the ceiling or walls by the crop being baled, or inward displacement of the ceiling or walls by the actuator system.

The needle gripper includes a thumb gripper rotatably mounted to a wall of the needle gripper. The thumb gripper rotates between a first position configured to secure the strap against a surface of the needle and a second position configured to release the strap from the needle. The needle gripper includes a release arm coupled to the thumb gripper and configured to rotate the thumb gripper from the first position to the second position in response to rotation of the release arm about a release arm axis from a neutral position to a first release position.

Abstract: A pressure roller for an apparatus for compaction of empty (disposable) hollow bodies (beverage containers), particularly plastic bottles or tin cans, having at least one rotating roller that is disposed at a distance from a counter-bearing, forming a gap, has an essentially cylindrical mantle surface that possesses multiple profiled partial regions of the same type and the same width in its working region, following one another in the axial direction. These profiled partial regions are separated from one another, in each instance, by a circumferential recess. Each of these profiled partial regions—viewed axially—has multiple sections that follow one another. At least one cam-shaped projection that projects radially away from the mantle surface is disposed in one of these sections.

Abstract: A reinforcing bar binding machine includes a wire reel which is supported on a binding machine main body, a feed motor which drives the wire reel, a twisting mechanism which twists and binds a wire, a twist motor which drives the twisting mechanism and a brake actuating unit which is actuated by the twist motor. The twist motor starts a normal rotation when the wire is fed by a predetermined amount. The twisting mechanism twists the wire to complete the binding after the twisting mechanism is advanced to a predetermined position by the normal rotation. The twist motor starts a reverse rotation after completing the binding, and the twisting mechanism is retracted to a stand-by position by the reverse rotation. Before completing the binding, the brake actuating unit brakes the wire reel to stop the wire reel and releases the braking with respect to the wire reel.

An equalizing reservoir supplies hydraulic fluid to the piston, and a transfer passage extends between the reservoir and the cylinder rearward of the piston. A fill valve has a displacement sleeve on a rod and carries a ring piston and a fill valve body movable centrally of the cylinder in the transfer passage between an open position in which the passage has a large annular flow cross-section and a closed position in which the valve body blocks the passage.

Abstract: There is provided a press machine which can apply a large compression force to a mold as well as impart smooth vibration only in a rectilinear advancing direction to the mold, and thereby can improve the press-formability. A main slide and a sub-slide constitute a slide and at the same time a cylinder-piston mechanism. During press-forming, a compression force is transmitted to the sub-slide (an upper mold) through hydraulic pressure applied interlockingly with driving of the main slide, and the sub-slide is vibrated with the hydraulic pressure being periodically changed. Favorable press-forming can be performed even under relatively difficult press-forming conditions, by controlling the vibration such that a vibration frequency of the sub-slide (the upper mold) becomes 9 Hz or higher but 33.3 Hz or lower and a vibration amplitude of the sub-slide becomes 0.05 mm or larger but 0.5 mm or smaller.

Abstract: A press machine includes a servo amplifier configured to supply a drive current to a servo motor, a current detector for detecting the drive current, a rotational angle detector for detecting a rotational angle of a rotary motion provided by the servo motor, and a controller. The controller is configured to set a press production speed by setting a correspondence between rotational angles and rotational speeds at the rotational angles, which defines the rotary motion. The controller is configured to determine whether or not the drive current detected by the current detector is greater than or equal to a first threshold. The controller is configured to reduce all the rotational speeds by an equal ratio when the drive current detected by the current detector is greater than or equal to the first threshold.

Abstract: A rotary stamper includes an upper die plate assembly, a lower die plate assembly, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway while moving the lower die plate along a linear horizontal pathway. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods that extend from the lower die plate assembly up through the upper die plate. In operation, the lower die plate matches the horizontal movements of the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper die plate moves towards and away from the lower die plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.
