  • Patent number: 5737988
    Abstract: A media buffer capable of buffering two lengths of media, is fed a first length of media from an imagesetter at a first speed, and releases the media to a processor at a second speed. An input media sensor senses the media entering the buffer. Drive rollers take up the leading edge of the media at the imagesetter speed. Shortly thereafter a signal from an output media sensor located between the drive rollers and the processor, opens an input door to an input bin and stops the drive rollers. The incoming media continues to be fed by the imagesetter forming a first slack loop within the input bin. The imagesetter signals the buffer that the media has been cut, thereby actuating drive rollers to advance the media at the processor speed to a pair of rollers in the processor. A signal from the processor sensor opens an output door to an output bin. The drive rollers increase speed to transport the first piece of media from the input bin to the output bin thereby forming a second slack loop.

  • Patent number: 4799413
    Abstract: A cutting arrangement for the cutting to shape of a web-shaped material, such as paper webs (2) in printing presses. The arrangement consists of a cutting element (8) and a backing element (3) over which the paper web runs, in conjunction with which one edge of the cutting element (8) is brought intermittently into contact with the paper web for the purpose of cutting through the paper web in its longitudinal sense. The cutting element (8) is so arranged as to change its position intermittently in relation to the paper web (2) between a first, advanced position in which the cutting element (8) uses its edge to cut through the paper web as it passes over the backing element and a second, withdrawn position in relation to the paper web in which the cutting element is not in contact with the paper web. The intermittent movements of the arm between the first and the second position are controlled by a control unit (12) depending on the advance of the paper web (2).

  • Patent number: 4755250
    Abstract: The process and the appropriate apparatus for producing rigid foam elements, in particular of polyurethane, operate with a double-belt unit, in which the rigid foam elements produced are provided with upper and lower cover sheets. A parting agent is applied on the lower cover sheet in a particular region in order to permit subsequent removal of the upper cover sheet and the ridge foam in this region, so that the lower cover sheet projects, and foams an overlapping section during subsequent use as a roofing element or the like. The invention permits a very precise cut to be made by means of the sawing apparatus at the end of the double-belt unit, taking into account the application of parting agent at the beginning and, if necessary, the movement of the sawing apparatus itself.

  • Patent number: 4737904
    Abstract: A standard-length positioning apparatus wherein acceleration and deceleration of a driving mechanism for actuating a mechanism for feeding a material is controlled by a digital positioning mechanism according to a position feedback. Marks marked on the material are read by a sensor during the deceleration of the driving mechanism, and the digital positioning mechanism outputs a signal for stopping the driving mechanism when it receives the read-in output of the sensor while the driving mechanism is being decelerated. When a signal from the sensor is not received by the digital positioning means while the drive is being decelerated, the digital positioning mechanism utilizes feedback pulses of a positioning detector to stop the drive.

  • Patent number: 4727787
    Abstract: Structural steel measuring apparatus comprises a reversible powered roller conveyor for advancing the structural member in opposite directions relative to a work station and a carriage movable alongside the conveyor and releasably clamped to the end of the structural member by an electromagnet. The carriage mounts a TV camera which reads an elongate scale extending alongside the conveyor. The reading is displayed on a monitor at the work station. The structural steel member can be positioned accurately with respect to the work station by driving the powered conveyor in either direction with the carriage magnetically coupled to its end. After the desired operation is performed, the carriage is decoupled from the structural steel member which is then advanced away from the work station by the conveyor.

  • Patent number: 4648862
    Abstract: Apparatus is provided in which booklets of interleaved cigarette papers can be made from continuously moving strands of strip paper in which a cutting knife used to sever the paper strips precisely follows movement of the strip. Movement of a driven input shaft is brought onto the moving platform and used to operate the cutting knife. Paper from bobbins is converged by formers and a spreader into a strand advanced by nip rolls through a cutting station. The knife in the station cuts a booklet from the strand while the station moves with the strand. A driven rotatory shaft of non-circular section transmits its rotation to a sleeve that slides therealong as the station reciprocates relative to a shaft. The sleeve is operably connected e.g. by gearing or by a cam and follower to the knife so that rotation thereof brings about the cutting movement.
