And the size is such that the head duct can be inserted without interference, and the moving table 71f is moved to insert the thrust paddle? /A'
By acting on the end of the i-reel B1, the reel can be pulled out from the core as described later.

In the device described above, a set of safety and positioning limit switches are provided for the operating purposes described below.

The device 10 is arranged to be held in the position indicated by the core or mandrel Al and to extract from the core a stick or roll of web B1 which has been wound on the core as described above by means of a winding device 5. When the roll or stick wound by the winder Hf1ts is sent as shown by the arrow f9 and reaches the slit grooved sheet 12, it is moved to the left in the drawing by the paddle wheel 1,
It reaches a position past the header of core A1 with reel Bl. At this position, the appropriate limit switch is activated and outputs a signal. That is, the roll or stick to be removed from the core reaches the position indicated by B,
When the core is located on the sheet saw and a suitable photovoltaic sensor or other detection device detects this condition, the loaded kg!
, g7 pushes the movable stage l, and brings the paddle 711 and f close to the end of the roll B1, and positions it between the end of this roll Bl and the groove A6 at the end of the core A1. This paddle? The position /A, that is, the position of the moving table 71, is limited by the contact of the pawl 5 on the moving table 71 with the stopper hook pushed out by the cylinder piston device 9. The displacement of the moving table 71 is 1K.
This is determined by releasing the brake motor 70f, which otherwise remains blocked in the tractionally active position of the carriage 71. After the movable base 71 is stopped by the stopper 77 in a new state using the chain for positioning the movable base 71 described above, the motor 70 is blocked again, and then the mounting hgq that was raised or lowered. The protruding piece g9A engages in the groove between the mandrel Al and its head A'F. When the device g9 reaches this position, the stopper 77 is retracted and the motor 70 moves the carriage g++ in the direction of the arrow fx via the chain 69.

The thrust paddle 7/A slides the stick or roll Bl and extracts it from the core by the sb of the moving table 71, and during this time, the fork-like protrusion gqA holds the core or mandrel Ali by the engagement action with the head A7. The mandrel has a friction effect, a fork-shaped protrusion &?
Due to the shape of the head A7 relative to A and the supporting action provided by the reel or stick B1, the stick is completely removed from the mandrel Al:
When the stick is completely removed, the mandrel A falls through the longitudinal slit of the sheet saw and enters the hopper/dam, where it passes through the conveyor 16 and It returns to Reservoir Park KM via slope 19. The movable platform is moved back by the motor movement Q, reaches the rearmost position, and the paddle?
/A returns to position in the area where the new reel and new core fall, as indicated by the arrow, and the cycle begins again.

In the above-described embodiment, the A dollar qih @ is positioned between the end of the stick B1 that is lowered and entered and the fork-shaped protrusion g9A, leaving a sufficient gap between the roll B and the groove A5. It is also possible to position the moving table 71t.

In the embodiment described above, it is arranged that the roll is axially displaced from the front 9 of the machine limited by the machine frame 6/, during which time the core falls into the hopper/4C.

FIG. 7 shows an example in which the roll is maintained at 4J4+1 before operation of the winder and the core or mandrel is moved in the ltl'l&1 direction.

According to the embodiment shown in FIG. 7, the outer casing 10 of the winding machine
