Abstract
1,206,133. Covering cores by winding. J. BAER. 6 Sept., 1967 [19 Sept., 1966], No. 40771/67. Heading B8G. Wound hollow bodies of fibre-strand reinforced synthetic resin are made by winding a band of fibre strands on to a rotating mandrel 1 whilst moving the band to and fro along the mandrel by a carriage 2. The carriage is driven by drive means comprising an hydraulic motor 40. A primary counter 85 is provided to count electrical signals and emit secondary impulses which are transmitted to a secondary counter 86 which then emits signals at preselected intervals to a digital-analog converter 87, 88, 89. The signals are thereby converted into analog voltage signals and utilized for the subsequent control of the hydraulic motor 40. The ratio of electrical impulses received in the primary counter to the impulses transmitted is settable to any desired value. As shown, hydraulic motor 12 drives the mandrel 1 via steplessly adjustable gearing 9 and gears 14, 15, 6 and 7. The impulse transmitter 17 is driven from gears 15 via step gearing 16. After a predetermined number of impulses are counted at 85, and secondary counter 86 has counted a predetermined number of the secondary impulses, step motor 87 is rotated through preset angle to operate servo valve 88 and hydraulic motor 89 and carriage position-control transmitter 90. The latter parts comprise the digital-analog converter. The transmitter 90 operates hydraulic motor 40 via amplifier 91 and valve 41. The distance that carriage 2 is driven is corrected by the transmitter 100 operating via the amplifier 91. Control of carriage reversal speed is achieved at the ends of the mandrel by carriage detecting transmitter 102 feeding signals which slow down the motor 40, when the transmitter 102 engages stop pins 106 or 107 on the carriage support. Preferably the speed of the carriage is slowed sinusoidally by transmitter 102. Control of transverse movements of the yarn guide 62 is possible so as to displace this guide towards the centre of the mandrel and transverse to the length thereof. When a control impulse is emitted from the secondary counter 86 to valve 24, the clutch 22 is engaged so as to connect control shaft 21 to the mandrel drive. This turns cams 25, 29, 31 and 32 causing guide eye position-control transmitter 39 to flow pressure medium into hydraulic cylinder 68 thereby moving the yarn guide 62 toward the centre of the mandrel. The movement of yarn guide 62 is corrected by transmitter 81. When point P on cam 31 is reached transmitter 39 acts in the reverse direction so as to return guide 62 to its initial position and a limit switch (not shown) disengages the clutch. Periodic acceleration of winding mandrel can be achieved when winding the bases of the mandrel by control valve 30 speeding up mandrel drive motor 12 during rotation of the control shaft 21. Yarn guide rotation about its support shaft 74 when the ends of the mandrel are being wound can be achieved by actuating hydraulic motors 70 via valve 72 and secondary counter 86.
