The tape-advancing mechanism comprises a driving force-converting device for converting a driving force received from the driving member to a driving force for use in tape-advancing motion of the tape-advancing mechanism, such that speed of the tape-advancing motion is varied as the tape-advancing mechanism is driven by the driving member.

Abstract: A control device for on the fly printing machines, especially machines for franking envelopes, comprises a printing device comprising a rotary print head actuated by a first motor and carrying on a portion of its surface a printing active part. A conveyor device for conveying the envelopes is actuated by a second motor and feeds the envelopes into contact with the printing device at a given conveyor speed and evacuates franked envelopes. The rotation speed of the first motor is optimized so that the tangential speed of the print head is held equal to the conveyor speed during a printing phase corresponding to the period during which an envelope is in contact with the active printing part and as close as possible to the conveyor speed during a complementary catch-up phase. The conveyor speed is optimized so that the conveyor speed is as low as possible whilst preventing overlapping of envelopes arriving on the conveyor device.

Abstract: A high precision strip film drive, typically for microfiche film, that includes two spaced-apart drive rollers, separately driven by two servo electric motors. The motors are biased against each other and so maintain a constant tension on the film, while it is stationary or moving.The motors are logic controlled through a pair of rotary encoders. Each encoder is driven by one roller. The outputs of the encoders are combined to give a single servo control signal, devoid of film squew, for accurately spacing the frames upon the microfiche.The encoder electrical outputs are differently handled to provide film velocity information, and still further differently handled to provide direction of motion of the film information.Transverse orthogonal motion of the film is provided by a carriage that supports the rollers, a linear encoder, and a cable system actuated by a third servo motor.The encoder electrical outputs are even further differently handled to accurately finally position the film, as preselected.

Abstract: A device for feeding a web like a microfilm by use of rubber rollers has a stepping motor for driving the rubber roller. The stepping motor is controlled by a pulse generator. A temperature detector is provided for measuring the temperature of the rubber roller or any part of the device having a temperature substantially equal to the rubber roller. The output of the temperature detector is sent to the pulse generator for controlling the stepping motor according to the measured temperature. When the temperature is raised, the stepping motor is controlled to reduce the speed of rotation and the increase in feeding speed due to expansion of the rubber roller is compensated, thereby feeding the web at a constant speed irrespective of the temperature fluctuation.

Abstract: A short dwell indexing drive system for intermittently moving a web of thermosealing material through a bag machine includes a conjugate cam defined by a pair of disc cams on a continuously driven input or cam shaft which engage cooperating groups of cam followers on an intermittently driven output shaft that yields one web draw/dwell cycle for each revolution of the cam shaft. In the preferred embodiment the contour of the cams smoothly index the web by first accelerating the output shaft from zero velocity through a relatively low peak velocity and thereafter decelerating the web to zero velocity at a point in the cycle in excess of 180.degree. before the output shaft is held stationary to the end of the cycle during a dwell period. Belt drives and an adjustable jackshaft which allows the use of different pulley ratios are connected between the output shaft and a web engaging draw roll for amplifying or reducing motion of the output shaft and for providing articles such as bags of different sizes.
