Abstract
A magnetic roller may comprise a magnetized outer surface and an internal chamber. A temperature control system may be in communication with the internal chamber, and a fluid capable of heat transfer may circulate within the internal chamber and the temperature control system. The magnetic roller may be used to produce magnetic sheets having magnetizable particles that are aligned according the a magnetic field generated by the magnetic roller. The magnetic sheet may be provided in a pliable form wherein magnetizable particles may shift orientation when exposed to the magnetic field. Heat may be transferred between the sheet and the magnetic roller to cause solidification of the magnetic material and prevent dealignment of the magnetic particles.
Claims29
A magnetizing roller comprising:
- a roller having a magnetized outer surface having multiple magnetic poles, the roller further comprising an internal chamber;
- a fluid arranged to circulate through said internal chamber;
- and
- a belt in proximity to the roller, the belt forming a closed loop, the belt positioned such that a sheet of magnetizable material in contact with the roller is sandwiched between the belt and the roller about a portion of a circumference of the roller.
A magnetizing roller comprising:
- a roller comprising an internal chamber and a magnetized outer surface having multiple magnetic poles;
- a temperature control system;
- a fluid arranged to circulate throughout said temperature control system and said internal chamber;
- and
- a belt in proximity to the roller, the belt forming a closed loop, the belt comprising a ferritic material, the belt positioned such that a sheet of magnetizable material in contact with the roller is sandwiched between the belt and the roller about a portion of a circumference of the roller.
A coating machine comprising:
- an extruder arranged to provide a continuous sheet of magnetizable material;
- a magnetizing roller having a magnetized outer surface and an internal chamber, wherein a heat transfer fluid is arranged to circulate throughout said internal chamber;
- a temperature control system in communication with said heat transfer fluid to maintain said magnetizing roller at a predetermined temperature;
- and
- a belt forming a closed loop, the belt arranged such that a portion of the sheet of magnetizable material is sandwiched between the magnetizing roller and the belt about a portion of a circumference of the magnetizing roller.
