Abstract
A tensioning device for materials of tape form particularly adapted for metic printers and comprises a floating element situated between free sections of a paper tape installed in return fashion in a driving mechanism. The floating element is provided with displacement transmission elements formed by spiked belts of which the spikes are engaged in perforations in the tape. The tensioning of the tape is provided by a weight hooked to the floating element such that the tape section emerging from the driving mechanism is driven, via the floating element, by the tape section which enters the driving mechanism.
Claims6
In a tape tensioning device for maintaining tension on a tape installed in a loop return fashion within a tape driving mechanism, said tape including a first free section arranged to enter the driving mechanism and a second free section arranged to leave the driving mechanism, the improvement comprising:
- a floating displacement transmission element for transmission of displacement disposed between the two free sections of said tape to enable the section emerging from the driving mechanism to be driven via this floating element by the section which enters into the driving mechanism;
- and
- tensioning means for said element arranged to cause said floating element to exert a pull on the sections entering and leaving the driving mechanism.
