A roving system (100) contains a first roving machine (1A) and a second roving machine (1B, 1C). The first roving machine (1A) includes a first roving winding mechanism (40A), a tension sensor (37A), and a first control section (41A) that controls the operation of the first roving winding mechanism (40A) based on tension control data. The second roving machine (1B, 1C) includes a second roving winding mechanism (40B, 40C) having the same machine specification as the first roving winding mechanism (40A) to spin the same type of the roving (R), and a second control section (41B, 41C), but not the tension sensor (37A). A plurality of roving machines (1A, 1B, 1C) is connected through a network (42). The first roving machine (1A) further includes a transmission section (44A) whereas the second roving machine (1B, 1C) further includes a reception section (46B, 46C). The tension control data is sent from the transmission section (44A) to the reception section (46B, 46C) so that the second control section (41B, 41C) controls the operation of the second roving winding mechanism (40B, 40C) based on the tension control data.

A special yarn spinning apparatus adapted for use in a spinning machine includes a plurality of apron draft devices that are configured to switch fiber bundles to be fed, respectively. The special yarn spinning apparatus further includes a joining device and an anti-twist device. The joining device joins a training end of the fiber bundle fed from at least one of the apron draft devices which has operated before switching the feed and a leading end of the fiber bundle fed from another of the apron draft device which has started after switching the feed. The anti-twist device holds and delivers the fiber bundle at a position downstream of the joining device to prevent propagation of twist from a twist device to the joined fiber bundles in the joining device.

A bobbin (18) for receiving roving has an internal shoulder enabling it to seat on a surface (22) provided at the upper end of a spindle (10). The bobbin hangs from this shoulder and the bobbin foot is received in a resilient clamp device (36) provided on the spindle for clamping a roving end against the bobbin.

This device comprises a spindle (4) for positioning the tube (5) on which the rove bobbin (8) will be formed, and a rotating flange (1), provided with an oscillating pressing finger (6), which rotates concentrically around the tube (5), said rotating flange (1) being responsible for twisting the rove (7) to be wound onto the tube (5). The rotational speed (St) of the tube (5) is lower than the rotational speed (Sf) of the flange (1), the pressing finger (6) being oriented towards the rear area of the flange (1) with the rotational direction of said flange (1) as a reference.
