Claims (19)

A method for producing a dense chopped strand having high density, characterized in that a flat chopped strand is produced to roll the flat chopped strand in a wet state to make the chopped strand tight. The manufacturing method of the high density chopped strand of Claim 1 which has a high density by oscillating the moving plate which carries a chopped strand, and performs a rolling effect. The method according to claim 1 or 2, further comprising the step of drying the high density chopped strands. 3. The chopped of claim 1 or 2, wherein the densified chopped strand is supplied to an area adjacent to one end of the vibrating moving plate, and the chopped in the form of a fluidized bed toward the other end of the moving plate while the chopped strand is vibrated. Moving strands and applying a heating gas to the fluidized bed of the cuffed strand from the savings such that the heating gas is flowed through the fluidized bed to dry the cuffed strands. The manufacturing method of the high density chopped strand which has. 5. The method according to claim 4, wherein the flow of cooling gas is applied to the fluidized bed of the cuffed strand from the bottom of the fluidized bed in an area downstream of the region where the heated gas is applied so that the coolant gas flowing through the fluidized bed is fed to the cuffed bed. Cooling the strand further comprises the step of producing a dense chopped strand having high density. The method of claim 1, wherein the wet flat chopped strand is supplied to one end region of the vibration transfer plate and moved to the other end region in the form of a fluidized bed during vibration to classify the rolling action to the chopped strand during movement. A method for producing a high density chopperd strand having high density. 2. The method of claim 1, wherein the heating gas is supplied to a layer of chopped strand flowing toward the other end on the vibration transfer plate, thereby allowing the chopped strand to dry through the layer from the bottom of the layer. A method for producing a high density chopperd strand having high density. 8. The layer of claim 7 wherein the cooling gas is applied to the top of the chopped strand that flows through the other end on the vibrating plate in a downward zone from the zone where the heating gas is applied. Method for producing a dense chopper strand having a high density characterized in that the flow through the cooling the chopper strand. 8. The high density choke with high density according to claim 6 or 7, wherein the heating gas is supplied to the fluidized bed area where the space is formed by a predetermined distance in a downward direction from the point where the wet chopper strand is applied. Method of making strands. 8. The method according to claim 6 or 7, wherein the heating gas is supplied to an area of the chopped strand fluidized bed adjacent to the supply point of the wet chopped strand. A rolling device having an inlet for receiving wet chopper strands, a rolling means for classifying the rolling action on the wet chopper strands, thereby tightening the wet chopper strands, and an outlet for discharging the treated chopper strands; High density chopperd strand manufacturing apparatus having high density. 12. The apparatus according to claim 11, wherein the rolling means includes a construction plate suitable for carrying the supplied chopped strand and a generator for vibrating the spheroidized plate. The apparatus according to claim 11 or 12, further comprising drying means suitable for receiving the chopper strands coming from the rolling means and drying them in the same manner. 14. The casing of claim 13, wherein said drying means is arranged in a casing provided with an inlet for the chopper strand at one end thereof and an outlet for the chopper strand at its other end, and horizontally at the one end and the other end. A perforated flow fixing plate having a plurality of small perforations, wherein the perforated flow fixing plate divides the space of the casing into at least one gas supply chamber below the perforated flow fixing plate and a gas discharge chamber above the perforated flow fixing plate; Vibrating means for vibrating the perforated flow fixing plate to move toward the exit while the chopper strand supplied through the inlet is vibrated; Heating gas supply means for supplying the heating gas to the gas supply chamber such that the heating gas flows upwardly through the perforation in the perforated flow fixing plate and then flows through the fluidized bed of the cuffed strand; And a gas discharge means for allowing a gas to be discharged through the gas discharge chamber. 15. The method of claim 14, wherein the second gas supply chamber disposed below the perforated flow fixing plate and on the downstream side of the first gas supply chamber in the flow direction of the chopper strand, the small gas perforated in the perforated flow fixing plate Apparatus for producing a dense chopper strand having high density characterized in that it further comprises a cooling gas supply means for supplying the cooling gas to the second gas chamber to flow upward through the fluidized bed of the chopper strand . 12. The apparatus of claim 11, wherein the rolling means comprises: a casing having an inlet at the end thereof for receiving the wet chopped strand and an outlet for the cuffed strand at an end thereof; A perforated flow fixing plate having a plurality of perforations disposed in the casing horizontally between the end and the other end, the perforated flow fixing plate being at least one of a lower portion of the perforated flow fixing plate through the space in the casing. A gas supply chamber and a gas discharge chamber on the perforated flow fixing plate; Vibrating means for vibrating the perforated flow fixing member to move toward the outlet along the perforated flow fixing plate in the form of a fluidized bed while the chopper strand supplied through the outlet is vibrated; Heating gas supply means for supplying heating gas to the gas supply chamber such that the heating gas flow flows upward through the perforations in the perforated flow fixing plate and then flows along the fluidized bed of the cuffed strand; A high density chopper with denseness that allows the cuffed strand to roll and dense and then dry while the cuffed strand moves along the perforated flow anchor plate by including gas discharge means for discharging the gas through the gas discharge chamber Strand manufacturing apparatus. 17. The apparatus of claim 16, further comprising: a second gas supply chamber positioned at a downstream side of the first gas supply chamber in the direction of the perforated flow bonding plate and the chopper strand; And a cooling gas supply means for supplying cooling gas to the second gas supply chamber so that the cooling gas flows upward through the perforations in the perforated flow fixing plate and then flows through the fluidized bed of the chopperd strand.
