A rigid yard refuse bag liner for insertion into a yard refuse bag for supporting the yard refuse bag in an open condition. The rigid yard refuse bag liner is an elongated enclosure having an open bottom and having a tapered construction such that its bottom portion is wider than its top portion, which facilitates the removal of the rigid liner once the refuse bag liner/refuse bag are filled with yard refuse. To further facilitate this removal, air vents running through the enclosure permit the passage of air as the rigid liner is lifted upward, out of the yard bag. A compactor is associated with the rigid liner whereby the compactor is a planar surface coupled to a handle that the user can grasp and apply pressure to in order to compact the yard refuse that has already been collected.

An apparatus for use in a press machine eliminates the free clearances present between the threaded portions of a screw and adjustment nut assembled in a shutheight adjustment mechanism. A hydraulic assembly directs a pressurized fluid against an outer periphery of the adjustment nut to effectively compress the adjustment nut and cause its threaded portion to be displaced into interlocking engagement with the threaded portion of the screw. Alternatively, the hydraulic assembly may be arranged to hydraulically pressurize an interior space of the screw to effectively expand the screw and cause its threaded portion to be displaced into interlocking engagement with the threaded portion of the adjustment nut.

A device for pressing the adhesive-glued areas of continuously conveyed, flat objects, preferably the bottoms of flat-laying bags. The device includes two dual belt conveyors running parallel to each other and mounted in a rack, and whose conveyor belts pressed against each other form pressing belts. To be able to quickly and easily adjust the pressing belts to a different position of glued areas to be pressed, at least one dual belt conveyor is mounted on a support or frame that is guided cross-sliding in the rack.

A positive lock for infinite adjustable stroke alignment mechanism for a mechanical press with an eccentric bushing disposed within a press connection member with a second eccentric member disposed within the eccentric bushing. A rotatable crankshaft is connected to the second eccentric member. A positive lock alignment mechanism is included for aligning the press connection member with the eccentric bushing to prevent rotation therebetween and permitting rotation of the second eccentric member with the eccentric bushing for infinite stroke adjustment whereby rotation of the crankshaft, when the mechanism is activated causes a press stroke adjustment.

A suspension mechanism is formed as a liquid-tight structure by fitting the bottom end of a female screw member using a liquid-tight sealing member provided between a slider and a retainer and by covering the retainer with the liquid-tight sealing member. A highly-pressurized liquid is initially supplied to each clearance formed between any components such as liquid-tight sealing member, female screw member, male screw member and retainer through a liquid supply passage formed through the liquid-tight sealing member. The highly-pressurized liquid is supplied by an amount flows out through the screwing portions between the male and female screw members to maintain the pressure of liquid within the liquid-tight structure in a predetermined range.

A press has a press plunger with an adjustable pressure piece. By way of an adjusting device, this pressure piece is supported on the remaining press plunger. A motor-operated tensioning device is additionally assigned to the motor-operated adjusting device. The adjusting device as well as the tensioning device are operated by force, that is, can be operated by corresponding drives. These are connected with a control device which coordinates the work of the adjusting device and of the tensioning device.

A press machine includes upper and lower slides respectivelly attached to upper and lower portions of posts movable in the up and down directions; a link mechanism having first and second levers connected with each other to cause bending and stretching motion, one lever having a first fulcrum connected with a frame, and the other lever having a second fulcrum connected with the lower slide, a connecting mechanism for connecting a crankshaft with the link mechanism such that the first and second levers are bent and stretched as the crankshaft is rotated; and an adjusting device for connecting with the link mechanism or the connecting mechanism such that the range of the bent angle made by the first and second levers can be adjusted.
摘要:
An apparatus for compressing objects includes a base plate, a frame and a ram head guided so as to be displaceable on the frame. Forces may occur in the peripheral direction of the ram head during the compression of bulky objects. The ram head is rotatable relative to the frame in order to reduce the forces introduced into the frame.
