Abstract: A device for releasing sections from a material web has a vacuum cutting cylinder and a counter cylinder for cutting the sections. The device also has a vacuum transfer roll for removing the sections from the vacuum cutting cylinder and a conveyor belt, onto which the sections are capable of being deposited from the vacuum transfer roll.

Abstract: In a ring-spinning machine having a frame and a spindle bank holding a row of bobbins, a bobbin-changing apparatus has a gripper beam engageable with the bobbins of the spindle banks and movable between an upper and a lower position and a scissor linkage pivoted on the frame and on the gripper beam extendable for raising the beam and collapsible for lowering the beam. The linkage has a pair of arms both of which have lower ends, one of which is long and has an upper end pivoted on the beam and the other of which is short and has an upper end pivoted on the long arm below the beam. One of the lower ends is pivoted on and fixed against longitudinal movement on an abutment. A guide is longitudinally displaceable on the frame and the other lower end is pivoted on it. A spring-biasing unit exerts torque on one of the ends of one of the arms for upwardly biasing the beam at least in the lower position of the beam.

Abstract: A method and apparatus for disposing an end of roving of a roving bobbin at a disposing location adjacent the drafting device of a spinning station of a textile spinning machine The roving end disposing apparatus, which is preferably mounted on a traveling service unit which travels to the spinning stations of the textile spinning machine to perform roving feed start operations thereat in which the feed of roving from a roving bobbin through a drafting device is started, includes a roving end support assembly for supporting a roving end for movement between a receipt location at which the assembly receives the roving end and the disposing location adjacent the drafting device at which the supported roving end is released either for engagement by the drafting device or piecing of the roving end with roving extending from another roving bobbin through the drafting device.
