Abstract
A drive unit is provided for powering a turret winding head for winding roving onto bobbin tubes. The drive unit comprises a closed housing, a first and a second spindle disposed in a turret base plate, wherein the turret base plate is formed as part of the housing and the spindles are disposed outside of the housing. A first drive is provided for the first spindle and a second drive is provided for the second spindle. The drives are disposed inside the housing, and the first and second drives are each provided with a fan wheel. An intake duct, through which air is drawn in by the fan wheel from outside of the housing, is in each case provided on the intake side of the fan wheel of the first and second drives.
Claims11
A turret winding head for winding a roving onto bobbin tubes in a roving frame, comprising:
- a closed housing;
- a rotatable turret base plate that forms part of the closed housing;
- a first and a second spindle disposed on the turret base plate outside of the closed housing;
- a first drive for the first spindle, and a second drive for the second spindle, the first and second drives disposed within the closed housing;
- and
- the first and second drives each comprising a fan wheel and a respective intake duct on an intake side of the fan wheel through which a suction air flow is drawn by the fan wheel directly from outside of the closed housing through the intake duct.
A method for operating a turret winding head for winding a roving onto bobbin tubes in a roving frame, the turret winding head including:
- a closed housing, a first spindle powered by a first drive;
- a second spindle powered by a second drive;
- the first and second drives disposed within the closed housing and each provided with a fan wheel, the method comprising:
- alternating an operating winding state of the first and second drives;
- and
- drawing outside air into the closed housing by the fan wheel of the operational one of the first or second drives through a filter and individual respective intake duct associated with the operational drive and connected directly between the operational drive and outside air through the closed housing.
