Abstract: A base film 9 on which a first pattern 31 is formed and a conductive foil 12 on which a second pattern 32 is formed are laminated by being passed through a gap between laminating rolls 7a, 7b which are provided with an adjusting means for adjusting the gap width and parallelism between them. Then, a relative position between the first pattern 31 and the second pattern 32 is detected. After patterning the conductive foil 12 to form a wiring 12w, displacements of the first pattern 31 and the second pattern 32 are detected, and the gap width and parallelism between the laminating rolls 7a, 7b are adjusted corresponding to the detected displacements. Thus, the laminate can be formed uniformly, and the base film 9 and the wiring 12 can be prevented from being deformed with the release of a residual stress in the patterning step. According to the manufacturing method of a high-precision film carrier tape, highly-integrated semiconductor devices are mounted with high productivity.

Abstract: A system of incrementally moving a foil, or other flexible and elastic elongated web, through a work station, by contacting and registering the foil on both sides of the work station. An example of such a work station is a hot stamping press that transfers optical images from the foil to other substrates.

Abstract: A main controller (55) causes a vision controller (36) to determine the exact location of plies (24) for a composite article in response to images from video cameras (35). The main controller then causes a robot controller (40) to direct a robot (42-46) to pick up the plies and move to a neutral position. The main controller causes the vision controller to determine that the plies were in fact picked up. If so, the main controller causes the robot controller to direct the robot to move the plies to the mold while the vision controller looks for the next ply to be picked up, in overlapped fashion. Failure to properly locate the plies and failure to verify that the plies were picked up causes an automatic retry to locate the plies or verify ply pick up.

Abstract: With the splicing get started, braking becomes strong and the old core decelerates, when the capstan roll comes to be free run. The speed reference to the second motor is a summed-up speed of "line speed minus capstan speed" and compensated portion of the tension. At once when the old core starts deceleration, the accumulation roll unit starts moving. The capstan roll is accelerated at a certain rate, when the new core is drawn out, up until the speed reaches "line speed plus overrun speed". When the accumulation roll unit reaches the synchronous position, the overrun becomes "0" and the capstan roll synchronizes with the line speed.
