摘要： The invention includes in one form a sewing machine, two trackers (mice) to track the ends of material-to-be-joined, and a controller for controlling stitch formation to achieve precise control of the material position, permitting desired easing (positive or negative). A long table is preferably used with a separation plate so that the two panels-to-be-joined can be laid out flat and separated during sewing. The mice slide in tracks so they will move in a straight line. The mice are adapted so that tension can be maintained and that the mice can be pulled back when the seam is done. Optical encoders are used so that the position of the mice, and thus endpoints of the panels, can accurately be determined. The sewing machine has an attachment that provides differential feed of the two plies in response to the desired and actual position of the stitches.

摘要： A system for locating a corner of an angularly oriented workpiece on a worksurface includes a gripper and associated two axis transport assembly, and a set of sensors on the gripper for detecting reflected radiation from the workpiece and surrounding work. A controller translates the gripper in the directions of two orthogonal axes until the sensors each overlie an edge of the corner-to-be detected. In the preferred form, the transport assembly includes a pneumatic position control system for each axis. Each pneumatic position control system includes an air cylinder and associated piston, a position valve assembly and a controller, and may further include a velocity valve assembly. The controller may control the position valve assembly to be in a first state during a selected time interval, thereby establishing axial motion of the piston in a first direction during that interval. Alternatively, the controller may control the position valve assembly to be in a second state during a selected time interval, thereby establishing axial motion of the piston in a second direction during that interval. The controller may also establish substantially no motion of the piston during a selected interval by alternately controlling the position valve assembly to be in its first state and its second state during the time interval. The velocity valve assembly controls the pneumatic impedance in the coupling path to the cylinder in order to selectively establish desired velocity for piston motion.

摘要： An automated system for selectively providing a limp material segment, e.g., fabric, to a joining apparatus includes at least one picker actuation mechanism ("PAM") for manipulating and transporting the segment. The PAM has an end effector for picking up the segment and an independently operable clamp for holding the segment while the PAM itself is transported between work stations.
