An inkjet recording device includes a conveying unit, a recording unit, a device main body, and a control unit. The conveying unit includes an endless conveyor belt having many air holes for sucking air, and a sheet sucking unit. The sheet sucking unit is disposed inside a loop of the conveyor belt, and includes a fan for sucking air through the air holes and a fan drive motor. The recording unit includes a recording head disposed to face an outer circumference surface of the conveyor belt, so as to eject ink from ink ejection nozzles to the paper sheet sucked and held on the conveyor belt. The control unit executes a paper dust removing mode during image non-recording time, in which it rotates the fan drive motor by a power higher than that when conveying the paper sheet, so as to remove paper dust in the device main body.

THREAD TRAVERSING DEVICE, THREAD GUIDE HOUSING AND METHOD

A thread traversing device for a winding device of a textile machine producing cross-wound bobbins comprising a thread guide housing having a thread guide, a traversing device arranged to reversibly traverse along a direction of the axis of the cross-wound bobbin, and at least one overpressure system having at least one fluid guide. The thread guide housing is designed, and the traversing device is associated with the thread guide housing, such that the thread guide reversibly traverses in a work station of the textile machine along a direction of the axis of rotation of the cross-wound bobbin. The thread guide housing can be brought into fluidic communication with the fluid guide in order to apply overpressure to the thread guide housing, and at least one defined exit point is designed and arranged in such a way that fluid can be diverted through the defined exit point.

THREAD TRAVERSING DEVICE, TEXTILE MACHINE AND METHOD

A thread traversing device for a winding device of a textile machine producing cross-wound bobbins including a thread guide housing having a thread guide, and a traversing device to reversibly traverse along a direction of axis of the cross-wound bobbin to be produced. At least one vacuum system comprising at least one fluid guide is provided, wherein the thread guide housing is designed and wherein the traversing device is associated with the thread guide housing so as to, in a work station of the textile machine, reversibly traverse the thread guide along a direction of the axis of rotation of the cross-wound bobbin to be produced, and wherein the thread guide housing can be brought into fluidic communication with the fluid guide in order to apply a vacuum to the thread guide housing.

Drive for a bobbin-winding machine

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.
