摘要： A drafting mechanism for a spinning machine containing a preliminary drafting zone and a main drafting zone is cleaned. There is provided an infeed roller pair comprising an upper roller and a lower roller, an exit or delivery roller pair comprising an upper roller and a lower roller, and an upper apron and a lower apron driven by an apron roller pair. The preliminary drafting zone extends between the infeed roller pair and the nip line formed by the apron rollers pressed against the upper and lower aprons, and the main drafting zone extends between this nip line and the exit roller pair. The lower apron extends beneath the preliminary drafting zone and the lower infeed roller. During operation of the drafting mechanism the lower apron is in grazing or wiping contact with the lower one of the infeed rollers. There is thus attained cleaning of the lower infeed roller and the lower apron without requiring special means for such cleaning. As a surprising result, substantially automatic threading-up of the drafting mechanism and recycling of fibers resulting from the cleaning operation are achieved.

摘要： An apparatus for the conjoint gripping of bobbins by means of pins or spigots formed of a rigid material, mounted at a support or carrier, and insertable into the bobbins. An expansible hose or tube member extends lengthwise of the support, this hose member when subjected to an increased internal pressure serving to press the bobbins against the pins or pin members inserted therein. This known apparatus has the advantage that there does not occur damage to the entering pin members, nor does there arise permanent deformation or destruction thereof. Yet, such apparatus possesses the shortcomings that the seized bobbins, when pressed against the pin members, are not positioned with sufficient accuracy in a direction parallel to the longitudinal direction of the support. The invention avoids such drawback in that, there are provided two straight edges at each pin member at the side thereof confronting the hose member, such too straight edges extending in the longitudinal direction of the related pin member and serving as contact surfaces for the bobbin pressed thereagainst.
摘要翻译：一种用于通过安装在支撑件或载体上并且可插入到筒管中的由刚性材料形成的销或插头来联合夹紧线轴的装置。可膨胀的软管或管件在支承件的纵向延伸时，该软管件经受增加的内部压力，用于将筒管压靠在插入其中的销或销构件上。该已知装置的优点在于，不会对进入的销构件造成损坏，也不会发生永久变形或破坏。然而，这样的装置具有这样的缺点：当被扣紧的线轴被压靠在销构件上时，在与支撑件的纵向方向平行的方向上没有足够的精度定位。本发明避免了这样的缺点：在每个销构件处，在与软管构件相对的一侧上设置两个直边，这些直边沿相关销构件的纵向方向延伸，并且用作用于筒管压紧的接触表面那边

摘要： According to the method, an end part of a roving is first introduced into the main drafting zone of a drafting frame of a textile machine after a reference point at a clamping device. Thereafter, a middle part of the roving is drawn laterally into the preliminary drafting zone solely by the tension of the main drafting zone. The apparatus comprises a gripper which is connected via a pivotable arm or a telescopic arm to a mobile or stationary robot which can cooperate either with a pusher, a spacer or a fixed slider.

摘要： A drive for the rolls defining a main drafting zone of drafting arrangements of long spinning machines, wherein in order to prevent drafting defects caused by distortion movement of the rolls, the latter are driven from one end by a first gear arrangement and from the other end are interconnected rigidly drivewise or slippage-free, respectively, during the standstill of the spinning machine via a second gear arrangement and via a freewheel clutch.
