tobe covered. This process and the devices already known for the carrying out thereof, possess the drawback that the particles of mica are not sufficiently separated from one another during the short passage from the conveyor band to thesieve. Several very thin particles frequently stick together, es pecially in damp air, and in. view of their thinness one can never be sure whether one or several particles thus adhere. If, however, several particles lying one upon another are brought upon the strip to be covered, the connection of the various layers is naturally a very imperfect one. Further, it is a drawback in this construction that special attendants or apparatuses are necessary in order to supply the mica to the con ve yer and to distribute it upon it somewhat uniformly. This is, however, important if it be desired to produce an article of uniform good quality. If a band of greater widthhas to be produced, then especial attention is necessary in order thatthe conveyer band may be uniformly covered. As it is diflicult to control the uniformity of the product, one is obliged to rely entirely upon the accuracy of the operator, which nevertheless 1 frequently proves unsatisfactory. In consequence iof the continuous working of the machine, the workman must not turn away his attention for an instant if he is to avoid irregularities in the covering of the strip. These drawbacks render it advisable that the supply of the mica to the movable sieve should also be effected automatically and as far as possible to arrange it in such a manner that the particles on their way to the sieve should be scattered one from another and be uniformly distributed over the surface of the sieve. In accordance with the invention this,
aspiration action is not only devised for the holding fast of the particles when brought in the neighborhood of the sieve to its surface, but also the particles themselves are to be sucked out-of their receptacle, and the distance from the receptacle to the sieve is made so long that the particles have time during the transit to separate one fromanother. The sub-division is obtained .more effectively, especially in damp air, when as pirated air is used. Moreover the air used can be brought again into the receptacle in order thereby to stir up and to dry the mica therein.
y The present invention also enables me by suitable proportioning of'the apertures of the sieve to aspirate the dust and the littleparticles out of the mass. 'Thedust' and small particles are drawn by the fan through the sieve, which sorts them, to a collector. This is of especial importance in the construction of plates of the kind which are used for the construction of insulating plates for accumulators. Moreover the insulating of all plates is greatly improved by this process.
The drawing illustrates a construction suitable for the carrying out of the inven tion' as follows:
Figure 1 shows a longitudinal section. Fig. 2 a plan view of the device.
. In these drawings adenotes the receptaclefrom which the mica flakes can be drawn. Attached to the receptacle over the whole width thereof, is a closed channel Z2, which descends to the movable sieve oZ traveling over rollers c, the rollers receiving their motion by means of'worm gearing from a motor. The sieve d is placed vertically to the longitudinal axis of the channel I). On the rear side of thesieve the channel is prolonged above the partition wall 9; in the suction tube 6, which leads to the fan 7". The air,
preferably warmed, passes into the recepta cle a through a slot g over against the channel b and extends across the whole width of the receptacle. The air also is driven into the container at from below by the fan as indicated by the arrows in Fig. 1, and passes through a heater m and the perforated bottom a so that the particles in the receptaole may be somewhat stirred up and at the same time dried and heated.
The method of working is as follows The I air aspirated by the fan 7 flows through the slot 9 above the uppermost layer of the mica in the receptacle a and carries with it the particles through the long channel '6 until they remain adherent to the sieve d. In consequence of the stirring up in thereceptacle meiny cpnvementmanner. As a relat1"vely large fsur-face of the sieve passes -=and" the channel, thelittle particles are separated from one -another and are Well distributed'jon'the sieve. From the sieve the flakes failf on the 'ba-nd 7, which can be arthr'ough the air channel 1), a veryuniform coveringtakesplace. Asfsoon asone hole of sieve passing at the-receiving poi'ntfand consequently frequently several holes remained uneovered.
The device can also be Worked by means of pressure air instead of suction, although the advantages in-this case do not equal those of the method above described.
' Having now described my invention, What I claim and desire to secure is:
A process of feeding mica sticking ma chines With the aid of aspirated air which consists in ca-using the flake of mice to be driven against screening means by said air,
and then deposited upon the adhesive plate, the air -being heated while passing" to the mic-a receptacle through a heating zone.
In testimony, whereof I have signed my name, to this specification; in the presence of -tW0f1subscribii1g l itnesses.
