$$ As the loop is shortened, the ram is extended to displace the further roller by the appropriate distance and prevent slack forming. (USP6672098)
$$ FIG. 9 shows an alternative embodiment in which pulleys 80 and 81 are installed and as the upper cable module is lowered 83, the additional cable slack is accommodated between the pulleys 82. (USP6655453)
$$ Accordingly as the mail item and the ribbon drawn thereby are fed past the print head, the ribbon between the print head and the take-up spool becomes slack and the flap 22 is freed to pivot anti-clockwise to a position as shown in FIG. 3. (USP5294203)
$$ Drive (43) to the take up spool is controlled by a pivoted member (22) which actuates a switch (26) to apply drive when the ribbon is slack and to terminate energisation of the drive as the ribbon becomes taut. (USP5294203)
$$ In this position of the flap, the lever of the micro-switch is released to permit the micro-switch to re-energise the ribbon is drawn by the feeding of the mail item, the drive to the take-up spool is repeatedly energised and de-energised to alternately tension and permit slackness in the ribbon. (USP5294203)
$$ When the tension in the material 8 falls the material 8 becomes slacker which causes the roller 90 to move downwardly in the slot 91. (USP4856692)
