Title: Method and apparatus for forming and collecting linear material
IPC: B65H67/048
Filed: 1959-12-22
Abstract: 902,584. Control of several A.C. motors. OWENS-CORNING FIBERGLAS CORPORATION. Dec. 22, 1959 [Dec. 29, 1956], No. 43566/59. Class 38 (3). [Also in Group IX] A device for winding filaments on bobbins (see Group IX) has individual motor drives to three bobbin arbors carried on an indexing head intermittently driven by a fourth motor to move an empty bobbin to winding position simultaneously with removal of a full bobbin from the winding position. Each bobbin motor is started in turn before being moved to the winding position and taken up to the speed of the motor that is about to move from the winding position, which motor will have varied in speed during the winding in order to maintain a constant take-up speed of filaments in spite of increase in bobbin diameter as winding proceeded. Each bobbin motor 82, 84, 86 when in winding position is controlled by an alternator 80 of a type in which the output frequency varies with speed of rotation and which is connected to the output component 78 of an eddy current clutch 76 driven by a constant speed motor 72 and including an energizing current coil 104 supplied from a thyratron control 106. A tachometer generator 100 normally maintains a constant value in the coil 104 through 106, 102 being a rectifier and 108, a voltage summating means or differential amplifier. The last mentioned is supplied with a reference voltage through a variable resistance 112 driven by a motor 116 under the control of a programmer 94 actuated by a control means 96, which may be a timer if winding time determines package size, or a pulsesensing device or counter if the number of revolutions of the bobbin being wound is to determine when the motors 82, 84, 86 are to be indexed. A motor 40 operates the indexing head 30 under control by a relay-controlled switch 98 connected to the programmer 94 which also supplies current to a motor 125 actuating a device for traversing the filaments across the bobbins being wound and to a motor 126 that gives a linear axial movement to a filament guide rod twice during each indexing sequence. Motor 82, 84 or 86 when in the position immediately preceding the winding station is put into operation just before indexing takes place and brought up to the speed of the motor at the winding station; after indexing, the speed is quickly brought to a maximum and then is slowly decreased according to the increase in bobbin diameter.

Each message includes a tone code, dialling instructions, e.g. pulses or tones, the message and a disconnect tone. The messages are stored on a multitrack magnetic tape used in a tape cartridge play back unit having a plurality of recording heads. The various parts of the device are shown in the drawing, the device is connected to the telephone exchange line at 30 and to the sensors at I 1 , I 2 , I 3  on lines 19, 20, 21. When a sensor operates, its associated relay in control logic 17 operates to disconnect the telephone instrument 29 from the line and to connect the output transformer of the device in its place. The tape deck motor is started and the reading head selected by means of play back head selector 15. The tone codes are replayed and operate a reed relay each of whose contact sets respond to a different frequency. If the frequency does not correspond to the right message a bi-stable circuit is set which opens the connection to line 30 so that dial information is not sent. If the tone frequency corresponds to the energized input then the bi-stable circuit is not operated and the reading head remains connected to the line through a transformer. The recorded dialling pulses are passed to an amplifier connected to a relay (K40, Fig. 2 (not shown)) which is operated to break the loop and transmit dialling pulses. Similarly when the disconnect tone is read, relay K40 operates to open circuit the line. The message is repeated to allow time for the called party to answer. The device is used in an intruder or fire alarm system.
