The extrusion apparatus includes a screw in a fixed barrel. The barrel has a feed inlet and an outlet with an extrusion nozzle which discharges into the nip between first and second rotary rolls that can rotate in opposite directions. The apparatus also has a first means for rotating and a first control means that are able to synchronize the speed of rotation of the first roll and the screw and has a second means that is able to rotate the second screw at a different speed of rotation than the first roll. The first control means can regulate the speed of rotation of the screw depending on the width of the strip, and a second control means can regulate the speed of rotation of the second roll depending on the thickness of the strip.

In one embodiment of an apparatus for manufacturing a rubber sheet, a continuous rubber material is supplied onto a supply conveyor in a meandering state by supplying the continuous rubber material onto the supply conveyor while moving rubber supply device in a reciprocating manner in a roll axial direction. The rubber supply device has a full width moving mode in which the rubber supply device moves in the roll axial direction such that the continuous rubber material has a meandering shape of a width corresponding to a width of a rubber sheet, and a partial width moving mode in which the rubber supply device moves in the roll axial direction such that the continuous rubber material has a meandering shape of a width obtained by excluding widths of both edge portions of the rubber sheet from the width of the rubber sheet.

A sheet manufacturing apparatus can easily adjust the stiffness of sheets made by the sheet manufacturing apparatus. The sheet manufacturing apparatus has a first material supply device that supplies a first material containing fiber; a second material supply device that supplies a second material containing fiber with an average fiber length shorter than the average fiber length of the first material; and a controller configured to control operation of the first material supply device and second material supply device. The controller has a first mode in which the first material is supplied from the first material supply device, and a second mode in which the second material is supplied from the second material supply device, and selects either the first mode or the second mode.

The present invention relates to a dough processing device, for use on a dough line, comprising dough processing means, such as a flour dispenser, a roller, a cutter, a folding shoe, for processing the dough on a conveyor; arranged in a frame, arranged for being placed as a bridge over a dough conveyor and thereto having supports at opposite ends; provided with fastening means, for fastening the supports on either side to a dough conveyor housing; wherein at least one support is provided with transport means, for transporting the dough processing device directly over a conveyor while supporting the dough processing device on said conveyor. The invention further relates to a dough processing line comprising such a dough processing device.

Disclosed are apparatuses and methods for forming films having uniform thicknesses across the entire width of the film. The films are also disclosed. The apparatus for forming the film includes a first nip roller and a second nip roller, each of the first nip roller and the second nip roller being configured to compress the powder as it passes between the first nip roller and the second nip roller and thereby form the film, whereby in the absence of a force counteracting the pressure of the passage of the powder between the first nip roller and the second nip roller the first nip roller is deflected to a greater degree than the second nip roller. Furthermore, the first nip roller and the second nip roller are each associated with one or more eccentric bearings that rotate to apply force vectors to the first nip roller and the second nip roller.

The present invention belongs to the technical field of control for rolling mill vibration, and particularly relates to a control device, system and method for vertical-horizontal coupling vibration of a corrugated rolling mill. The control device includes a housing; a vibration-absorbing container is arranged in the housing; a steel ball particle group is placed in the vibration-absorbing container; a left side of the vibration-absorbing container is connected with one end of a return spring; the other end of the return spring is fixedly connected with a third base; the third base is fixedly mounted on a third sliding block; and the third sliding block is slidably arranged on a third linear guide rail.

The present disclosure discloses a silica gel vibrating diaphragm and a method for fabricating the same. The method comprises: forming a composite material belt by using two layers of a base material and liquid silica gel in a calendering manner, wherein the liquid silica gel is between the two layers of the base material; wholly hot-press molding the composite material belt by a vibrating diaphragm die holder, a temperature of the hot-press molding being higher than a vulcanization temperature of the liquid silica gel; removing the two layers of the base material to obtain a whole sheet of silica gel vibrating diaphragm; and blanking the whole sheet of silica gel vibrating diaphragm that has been removed of the two layers of the base material to fabricate a required silica gel vibrating diaphragm. As compared with conventional solutions, the technical solution of the present disclosure has the advantages of simple molding manner, low cost, various styles of the vibrating diaphragm, and small thickness of the vibrating diaphragm.

An apparatus includes a first roll and a second roll on each of which a pattern is formed, a first motor and a second motor to rotate the respective rolls, a shaft direction supporting mechanism to support the second roll along a shaft direction and an axial position adjusting mechanism configured to move the shaft direction supporting mechanism along the shaft direction. The posture of the rotating shaft of the second motor is maintained constant at all times, and the second roll is moved in the shaft direction along the first roll, thereby adjusting the positions of both patterns on the first roll and the second roll along the shaft direction.

A multi-stage roll type sheet molding apparatus includes four or more molding rolls including a touch molding roll, a main molding roll and finish molding rolls disposed in the horizontal direction in parallel to each other, in which a molten sheet is supplied downward from above to a first nip part interposed between the touch molding roll and main molding roll, the sheet is compressed by the molding rolls, and the compressed sheet is windingly fed sequentially from the main molding roll to the finish molding rolls, thereby molding a sheet having a specific thickness. The apparatus further includes a rear-stage side rail for guiding the finish molding rolls in a horizontally movable manner and second to fourth hydraulic cylinders for horizontally moving the finish molding rolls to in such a manner that they can pressurize the sheet.

A thin film member forming device includes a reference roll fixedly disposed while being rotatably supported by a first bearing member, a movable roll disposed movably with respect to the reference roll while being rotatably supported by a second bearing member, a roll gap adjusting mechanism which adjusts a gap between the reference roll and the movable roll and a roll opening mechanism which expands the gap. The roll gap adjusting mechanism adds a load in a direction to narrow the gap to the second bearing member, and the roll opening mechanism adds a load in a direction to expand the gap to the second bearing member.
