Abstract: A cop individualizing apparatus operates a circular conveyor of the type having a helical cop guide track on a vibratory basis by providing two unbalanced electromotors whose speed is controllably varied via a frequency converter alternating between two frequency stages as a function of the instantaneous cop supply requirement of an associated cop dispensing device fed by the individualizing apparatus, in order to assure advancement of the cops along the transport track of the circular conveyor in precise relation to the particular instantaneous cop requirement.

Abstract: An apparatus for orienting packages of textile material into predetermined individual orientations cooperates with a package delivery system which delivers packages in random orientations. The package orienting apparatus includes a device for classifying each package on the basis of a detectably different characteristic such as, for example, the characteristic that one respective end of the tube of the package has a larger diameter than the other tube end. A disposing device is operatively connected to the classifying device for moving each textile material package through a predetermined movement in response to the sensing of the detectably different characteristic to thereby bring the package into a predetermined individual orientation. The disposing device can include a drum having a pair of package receiving elements formed therein each along a respective radius of the drum and perpendicular to the other package receiving element.

Abstract: The invention is in a process, and the apparatus, for path control of a processing tool of a grinding machine for an all-around edge grinding of a glass pane. A cross sled supports the processing tool for movement in an X-Y coordinate system wherein the path of movement of the cross sled is controlled by a program. The path control, however, is critically controlled by the use of a scanning instrumentality including a scanning organ which scans the edge of the glass pane along a path of movement in front of the processing tool. The scanning organ is supported by an arm articulated about the axis of the processing tool. The scanning organ leads the processing tool by a set distance, equal to the length of the arm, and determines the values for the X- and the Y-coordinates. The values that are developed by the scanning organ are stored in a sliding register having an input from each of the two axes.
