Patent number: 9890475Abstract: The present disclosure relates to a method and a device for application of liquid polymeric material onto the active spinning zone of the cord of the spinning member of the spinning electrode, where the application means moving reversibly along the active spinning zone of the cord in the device for production of nanofibres through electrostatic spinning of liquid material in electrostatic field of high intensity between at least one spinning electrode and against it arranged collecting electrode. The liquid polymeric material is applied onto the cord around its whole circumference without any contact with gaseous environment in the spinning space, where the application means reversibly moves, whereas while the cord is leaving the application means the thickness of the layer of the liquid polymeric material is being reduced and immediately after leaving the application means the process of electrostatic spinning of the liquid polymeric material applied on the cord is started.Type: GrantFiled: February 27, 2012Date of Patent: February 13, 2018Assignee: Elmarco S.R.OInventors: Miroslav Maly, Pavel Sejak, Vit Stromsky, Milan Nydrle, Michal Bittner, Ladislav Mares, Jan Cmelik, Lenka Hanusova, Martin Podany, Radim Krenek

Patent number: 9279195Abstract: A device for production of nanofibers through electrostatic spinning of the liquid matrix in electrostatic field between at least one spinning electrode and a collecting electrode positioned opposite thereto, while the spinning electrode contains at least one spinning member containing the cord, which comprises a straight section which is parallel with a plane of depositing the nanofibers and/or with the collecting electrode and it forms an active spinning zone of the cord. The cord of the spinning member is stationary or is displaceable in a direction of its length or is movable in a direction of its length either discontinuously or continuously and to the cord there is assigned a device for application of the liquid matrix on the cord in a direction of length of the cord.Type: GrantFiled: March 21, 2012Date of Patent: March 8, 2016Assignee: Elmarco, s.r.o.Inventors: David Petras, Miroslav Maly, Martin Kovac, Vit Stromsky, Jan Pozner, Jan Trdlicka, Ladislav Mares, Jan Cmelik, Frantisek Jakubek

Patent number: 8231822Abstract: Method for spinning the liquid matrix (38) in electrostatic field between at least one spinning electrode (3) and against it arranged collecting electrode (4), while one of the electrodes is connected to one pole of high voltage source and the second electrode is connected to opposite pole of high voltage source or is grounded, at which the liquid matrix (38) being subject to spinning is to be found in electrostatic field on the active spinning zone (3100) of the cord (310) of the spinning means (31) of the spinning electrode (3). The active spinning zone (3100) of the cord during spinning process has a stable position towards the collecting electrode (4) and the liquid matrix (38) to the active spinning zone (3100) of the cord is delivered either by application to the active spinning zone (3100) of the cord or by motion of the cord (310) in direction of its length.Type: GrantFiled: July 16, 2008Date of Patent: July 31, 2012Assignee: Elmarco, S.R.O.Inventors: David Petras, Miroslav Maly, Martin Kovac, Vit Stromsky, Jan Pozner, Jan Trdlicka, Ladislav Mares, Jan Cmelik, Frantisek Jakubek
