[0026]

In summary, according to the present invention, a pair of support arms are provided between both side frames, a support portion is rotatably provided on the support arms, and the beam is rotatably supported by the support portions. A drive shaft and a supporting portion, which are rotationally controlled by a drive motor arranged in the frame, and a connecting portion between the supporting portion and the bobbin winding shaft are arranged between both side frames and the disc of the beam, and In the beam machine where the space between both side frames is open to the front with respect to the anti-drum machine side,
Frames 37 and 37a extend horizontally from the opposite side surfaces 7a and 8a of both side frames 7 and 8 toward the anti-drum machine side at substantially the same height as the bobbin winding shaft 24 of the beam 20.
The base end of the blocking arm 39 is mounted on the rotary drive source 38 provided at the tip of the 37a, and the blocking arm 39 is controlled to swing from horizontal to vertical in a vertical plane, and the blocking arm in the horizontal state is also mounted. Since 39 is positioned in front of the outer peripheral edges of the discs 25 and 25a of the beam 20, the open space between the side frames 7 and 8 and the discs 25 and 25a of the beam 20 is blocked from the open side which is the side opposite to the drum machine. Since it can be blocked by the arm 39, the beam 20 and the drive motor 33 are exposed, and the worker's entry into the connecting portion X having a protruding portion and contact with the outer peripheral edges of the disks 25, 25a are mechanically performed. Alternatively, it is visually regulated to prevent accidents involving clothes from getting caught at the connecting point X to ensure safety during work, and the blocking arm 39 in the horizontal state is a bobbin winding shaft.
Since the height is approximately the same as 24, the isolation distance from the connecting point X can be set to the maximum, so that the above safety is further improved.

Further, since the tip end 39a of the blocking arm 39 in the horizontal state is provided with a predetermined space, the intermediate portion between the disks 25 and 25a of the beam 20 is opened forward without the blocking arm 39. Therefore, the warp thread W to be wound around the thread winding shaft 24
As described above, it is possible to arrange the threads without any support while ensuring the safety as described above, which is a great practical effect.
