A ribbon wheel ( 27 ) to which lengths of ribbon ( 22 ) from spools ( 65 ) are wound for ultimate severance into ribbon strands ( 29 ). Ribbon material ( 23 ) advances from posted spools ( 65 ) in compartment ( 61 ) of frame ( 36 ) of apparatus ( 20 ) to their collection at and through slot ( 67 ) in top panel ( 34 ) of frame ( 36 ) for apparatus ( 20 ). A post ( 66 ) in compartment ( 61 ) guides ribbon material ( 23 ) to slot ( 67 ). The collected ribbon lengths ( 22 ) are wound a number of revolutions upon the wheel's peripheral surface ( 25 ) formed between the wheel's discs ( 38, 39 ) by means of shaft ( 48 ) and handle ( 51 ) that rotates wheel ( 27 ). Recesses ( 31 ) in wheel ( 27 ) provide points at which the ribbon lengths ( 22 ) are severed after ties ( 85 ) tie them together at other particular recesses ( 31 ) to form multiple ribbon strands ( 29 ). A mechanism ( 75/74 ) is provided on frame ( 36 ) for curling ribbon lengths ( 22 ) prior to their introduction to wheel ( 27 ). A clip ( 78 ) is mounted on frame ( 36 ) to prevent slippage of ribbon lengths ( 22 ), integral to ribbon material ( 23 ), back through slot ( 67 ) after severance of them on wheel ( 27 ). A revolution counter ( 54 ) on frame ( 36 ) cooperates with its tripper ( 55 ) on wheel ( 27 ) to record the number of revolutions undertaken by wheel ( 27 ) from which calculation of the number of ribbon strands ( 29 ) may be made.
