A method of and a device for placing chip-type components on a substrate, in which a number of components are simultaneously picked up in presentation positions by means of a pick-up device which has a number of pick-up elements, after which the pick-up device is moved to a position over the substrate and each of the pick-up elements in succession is moved to a position over the desired position on the substrate by movement of the pick-up device and/or the substrate with respect to one another, after which the relevant component is deposited and released in the relevant position by the pick-up element.

Method of and device for placing chip-type electrical and/or electronic

A method for feeding chip components to positions in which they can be picked up by transfer members, in which the chips are pushed out of a feed channel while being held between an ejection pin and a transfer member part. An elongated part of a transfer member is advanced into a feed channel into contact with one side of a chip, an ejection pin then advances to the other side of the chip and pushes the chip and transfer member out of the feed channel through a removal opening, and the chip is then held by the transfer member while the ejection pin retracts. Preferably, a cover plate prevents movement of the chips toward the transfer member until the member is in contact with the side of the chip.

A claw mechanism for the transport of a film in a film projector. A claw arm is disposed parallel to the transport path and pivotable about an axis transverse to the direction of transport; a claw means is disposed substantially transverse to the transport path, pivotally connected to the free end of the claw arm about an axis transverse to the direction of transport; and a drive shaft disposed parallel to said two axes, which rotates continuously during operation, comprises a crank which engages a slot in the claw means. A cam follower, pivotally connected to the free end of the claw arm about an axis parallel to the direction of transport, is pressed against one of two cams on the drive shaft by spring force and is connected to the electromagnetic control means for engagement alternatively with a first cam for keeping the film perforations out of engagement with the claw means, or a second cam for intermittently advancing the film by one frame per revolution to control the movements of the claw arm and thus the speed of film transport.
