Definitions

  • This invention relates to an adhesion drive for a tapesh-aped signal carrier adapted to be fed through a signal recording or signal reproducing apparatus, such as a mag netic sound tape, a perforated tape or the like, wherein the speed of the signal carrier is controlled by contact thereof with a rotating cylinder.
  • FIG. 1 is a fragmentary, enlarged sectional view showing a portion of the driving cylinder engaged by a tape;
  • FIG. 2 is a similar view illustrating the manufacturing process utilized to embed the diamond particles in the driving cylinder.
  • FIG. 3 is a plan view illustrating a pressing roller urging the tape into contact with the rotating driving cylinder.
  • the driving cylinder should be made of a relatively soft, stainless material such as unhardened stainless steel, coppenbrass or a plastic material,- diamond particles having a size in the order of 20 to p. for a cylinder diameter of 5 to 10 mm. being rolled into the surface of the driving cylin der in such a manner that approximately half the particles project from the surface of the cylinder.
  • the sizeof the particles may increase with increasing diameter of the driving cylinder, and the size should be chosen in such a way that fluctuation of the driving speed is impossible due to inequalities in the engagement of the tape with the particles.
  • a pressing roller should be used having an axial length not exceeding the width of the tape as shown in FIG. 3 in order that the roller contacts the tape only and not the driving roller. It was found that a roller contacting the tape and the driving cylinder often causes deviations of the tape speed from the circumferential Speed of the driving cylinder because the tape is driven by the pressing roller. It is a particular advantage of this invention that the driving cylinder is practically not worn due to the absence of slip and due to the high hardness of the particles forming the driving surface.
  • Manufacture of the driving cylinder is relatively simple. However, some important indications mentioned here after should be followed.
  • the surface of the cylinder is to be worked, for instance ground, to be very smooth.
  • a pasty substance contain- I slowly approached to a distance in the order of of a millimeter from the cylinder surface, whereby the pasty substance is first equally distributed on the cylinder surface without pressing the hard particles into the cylinder surface.
  • the roller is further approached substantially into contact with the surface of the driving cylinder whereby the particles are rolled into the relatively soft cylinder surface.
  • the hardened outer race of a ball bearing may be used as a pressure roller, this ball bearing being tixcd on a slightly resilient support. During this operation the speed of the cylinder surface should be relatively low and should not exceed 10 cm./sec.
  • This invention may be used in all kinds of apparatus used in sound-picture production, in magnetic picture recording machines for television, and for automatic control of machines by means of perforated tapes or the like, wherein the higher precision and the longer lift-time of the drive are very important.
  • the drive may also be used where the cylinder is not driven by a motor and does not drive tie tape, but where the cylinder is driven by the tape.
  • Such an arrangement is used when equalizing the speed of tapes fed by means of toothed rollers engaging perforations or" the tape, such tapes being fed over an adhesion cylinder connected to a flywheel, the adhesion cylinder and flywheel equalizing fluctuations of the tape speed due to the drive thereof by means of toothed rollers.
  • the long life-time of the rough surface of the driving cylinder is of particular advantage for machines used for producing tape copies from an original, such machines having very high running times of up to 24 hours per day.
  • An adhesion drive for a magnetic recording tape having an active layer comprising individual particles of magnetizablc material at one side of said tape comprising a rotating cylinder and means for maintaining the said tape in contact with the rotating cylinder in order to maintain the speed of the tape equal to the circumferential speed of the rotating cylinder, the said cylinder having a. smooth cylindrical surface, hard particles being partially pressed and thus anchored in the said surface of the cylinder, the remaining portion of the particles projecting from the said surface and contacting the active layer of the said magnetic recording tape, the said hard particles having a size in the same order as the size of the individual particles of the said active layer.
  • An adhesion drive for a recording tape comprising a rotating cylinder having a smooth cylindrical surface and means for maintaining the said tape in contact with the cylindrical surface of the rotating cylinder in order to maintain the speed of the tape equal to the circumferential speed of the rotating cylinder, hard particles being anchored in the said cylindrical surface of the rotating cylinder with portions of all particles being inserted into the cylindrical surface to an equal depth, the remaining portion of the particles projecting from the cylindrical surface and uniformly contacting the tape on the cylindrical driving surface.
  • An adhesion drive for a recording tape comprising a rotating cylinder having a smooth cylindrical surface and means for maintaining the said tape in contact with the cylindrical surface of the rotating cylinder in order to maintain the speed of the tape equal to the circumferential speed of the rotating cylinder, hard particles having a size of less than 1 being anchored in the said smooth cylindrical surface of the rotating cylinder with portions of such particles being inserted into the cylindrical surface of the rotating cylinder, the remaining portion of the particles projecting from the cylindrical surface and contacting the said recording tape, said particles being substantially uniformly distributed at random on said smooth cylindrical surface.
  • An adhesion drive according to claim 3, comprising a rotating cylinder of stainless steel.
  • An adhesion drive for recording tape comprising a metallic rotating cylinder having a smooth cylindrical surace and means for maintaining the said tape in contact with the cylindrical surface of the rotating cylinder in order to maintain the speed of the tape equal to the circuinferential speed of the rotating cylinder, the said cylindrical surface having a diameter in the order of 5-10 mm. and hard particles having a size in accordance with the said diameter of the cylindrical sunface in the order of 20-100, being anchored in the said cylindrical surface of the rotating cylinder with portions of such particles inserted into the cylindrical surface of the rotating cylinder, the remaining portion of the paiticles projecting from the cylindrical surface and contacting the said recording tape.
