Apparatus and method for manufacturing rubber sheet
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.
Sheet manufacturing apparatus and sheet manufacturing method
A sheet manufacturing method includes defibrating a defibration object into a defibrated material in the atmosphere, mixing, in the atmosphere, additive agents including resin into the defibrated material that has been defibrated, adding moisture to a mixture of the defibrated material and the additive agents after the mixing is completed, and heating the mixture that has been moisture-added.
FILM HAVING A WOOD-LIKE APPEARANCE
The invention relates to a film having a wood-like appearance and having a width from 0.1 to 6 m, a length of 2 to 10,000 m, a thickness from 180 to 1,000 m and formed from, a material which contains, relative the total weight thereof 40 to 85 wt % of vinylchloride polymerizate, 10 to 60 wt % of a powder made from vegetable components, 0 to 30 wt % of one or more inorganic filler substances, and 5 to 30 wt % of one or more additives.
SHEET MANUFACTURING APPARATUS
A sheet manufacturing apparatus includes an impeller mill defibrating, in a dry process, a raw material containing a fiber, a mixer mixing a defibrated material and a resin, using an air stream to produce a mixture of the defibrated material and the resin, a sieve having an opening through which the mixture passes, a belt, a heater, and a nozzle. The mixture is accumulated on an upper side of the belt to form a web. The heater heats the web to form a sheet so that the fiber is bonded by the resin. The nozzle is arranged between the belt and the heater and applies a liquid to a partial portion of the web so that bonding between the fiber and the resin in a first portion of the sheet is weaker than bonding between the fiber and the resin in a second portion of the sheet.
SHEET MANUFACTURING APPARATUS AND SHEET MANUFACTURING METHOD
A sheet manufacturing method includes defibrating a defibration object into a defibrated material in the atmosphere, mixing, in the atmosphere, additive agents including resin into the defibrated material that has been defibrated, adding moisture to a mixture of the defibrated material and the additive agents after the mixing is completed, and heating the mixture that has been moisture-added.
Method and apparatus for forming marbelized engineered stone
An apparatus including a first dispensing device configured to supply a first material to a conveyor belt of the main conveyor device in response to control by the computer processor, and a second dispensing device configured to supply a second material on top of the first material, while the first material is on the conveyor belt to form a combination comprised of at least the first and second materials, in response to control by the computer processor. The combination may be compressed by a first compression device in response to control by the computer processor. The compressed combination may be stirred by a first stirring device in response to control by the computer processor to form a first modified combination. The first modified combination may be compressed by a second compression device in response to control by the computer processor to form a compressed first modified combination.
Sheet manufacturing apparatus and sheet manufacturing method
A sheet manufacturing method includes defibrating a defibration object in the atmosphere, mixing, in the atmosphere, additive agents including resin into a defibrated material that has been defibrated, adjusting moisture of a mixture of the defibrated material and the additive agents, and heating the mixture that has been moisture-adjusted.
Method of shortening the time to compression mold a roofing shingle or tile and apparatus for facilitating same
A method of shortening cycle time required to compression mold shingle or tile is provided, wherein carrier plates are comprised of a surface material and a base, and receive a thermoplastic material, thereon. The roofing material is applied to the carrier plate and the carrier plate is subjected to induction heating, by which its surface material has its temperature raised, without substantially raising the temperature of the carrier plate base, such that the thermoplastic material applied thereto is kept heated in the compression mold. Cooling of the thermoplastic material is by heat transfer from the carrier plate surface material to the carrier plate base, and with both materials having good heat conduction capability. The carrier plate surface material has a high receptivity to being heated by induction heating relative the carrier plate base. The carrier plates are serially delivered through the process, to the compression mold.
Method for manufacturing three-dimensional netted structure
A three-dimensional netted structure having an upper surface, a lower surface, two side surfaces a left end surface, and a right end surface, including at least a plurality of filaments helically and randomly entangled and thermally bonded together, wherein the filaments are formed out of a thermoplastic resin by extrusion molding followed by cooling with a liquid; and the netted structure is four-surface molded, the upper surface, the lower surface and the two side surfaces being molded. An apparatus and a method for manufacturing the three-dimensional netted structure.
Molding of fiber blanks into three-dimensional fiber block articles
A fiber block molding apparatus comprising: a mold having a lower part and an upper part forming between them a cavity for forming a fiber blank into a fiber block article upon closing the mold; a conveyor system for receiving the fiber blank to be molded at a receiving position, transporting the fiber blank via a heater for activation of a binding agent, and delivering the heated fiber blank into the lower part of the mold at a delivery end of the conveyor system, and a horizontal position shifting arrangement for shifting the horizontal position of the delivery end of the conveyor system relative to the lower part of the mold between a first and a second position to lay the fiber blank on the lower part of the mold.
