Abstract: A winding apparatus for winding a continuously advancing yarn to a package. In this process, the yarn is reciprocated by means of a rotary blade type traversing apparatus along a predetermined traverse stroke. In so doing, the yarn is alternately guided within the traverse stroke along a guiding edge of a main guide plate and along an opposite guiding edge of an auxiliary guide plate. The guiding edge of the main guide plate and the opposite guiding edge of the auxiliary guide plate extend through the traversing plane in opposite directions. The auxiliary guide plate is movable transverse to the traversing plane such that the opposite guiding edge of the auxiliary guide plate extends to a lesser extent or does not extend through the traversing plane.

Abstract: A motor-operated hand-held device (1), such as a drilling device, has a rotary spindle 6 located in and projecting out of a housing (2). Rotational movement of a driving motor (8) is transmitted to a tool (7) situated in an end of the rotary spindle (6). A safety device (11) within the housing (2) prevents deflection of the housing about an axis (A) of the rotary spindle (6) in the event the tool (7) becomes suddenly jammed. The safety device (11) can be activated by a detection device (12) if the tool becomes jammed. The safety device (11) is located inside the housing 2 adjacent to the rotary spindle (6) and is formed of at least two component parts which cooperate in frictional engagement in the event the device is activated. One of the component parts is connected to the housing (2) and the other is connected to the rotary spindle (6).

Abstract: A motor-operated hand-held device (1), such as a drilling device, has a rotary spindle (6) located within and projecting out of a housing (2). Rotational movement of a driving motor (8) is transmitted to a tool (7) secured to the end of the rotary spindle (6). A safety device (11) within the housing (2) prevents a deflection of the housing about an axis (A) of the rotary spindle (6) in the event the tool (7) becomes suddenly jammed. The safety device (11) can be activated by a detection device (12) if the tool (7) becomes jammed. An overload slip clutch (10) is provided in the drive (9) between the driving motor (8) and the rotary spindle (6). The safety device (11) is arranged in series with the overload slip clutch (10) and is located in the drive (9) adjacent the overload slip clutch (10). When activated, the safety device (11) couples the housing (2) with the drive (9) for the rotary spindle so that the housing (2) and the drive (9) are fixed with respect to rotation relative to one another.
