もって。[Detailed Description of the Invention] The present invention is a paper feeder for a thread binding machine, in which the lower part is opened to the left and right by a device, and the folds are placed in the middle on a mountain-shaped saddle. In order to prevent the inside stickers and folded pieces of the folded sheets on which the inside stickers and endpapers have been attached from being mistakenly sorted into the opposite direction of the required direction, the signatures with inside stickers and endpapers are attached. The motor should be rotated at a low speed only when sorting.
Take it.

確実に折丁がサドル上に跨架されるようにした可変速給

るようにしたものである。The thread binding machine straddles the folded folded sheets in an open state over the chevron-shaped saddle of the paper feeder connected to the machine, and feeds the folded sheets into the chevron-shaped saddle of the thread binding machine by means of a feed roller. The binding thread is fed onto the upper plate of the folded sheet, and after passing through this upper plate, the binding thread is inserted through the spine of the signature.

When the signature S is delivered one by one by the delivery roller B and sent onto the saddle E by the auxiliary feed roller C9C and the feed rollers D and D, the lower end sides of the signature S are held by the suction bodies F and F, as shown in the third figure. It is sufficient to suction it outwards, open it, and drop it onto the saddle E as it is.

折丁Ｓ′ 。However, the signatures sent by the feed rollers D and D of this paper feeder are not signatures with an inner patch S3 or a facing S4.
//, as described above, the shaft 8 is rotated by the card device, and the cam 9 provided on the shaft 8 causes the normally open state in the low speed winding circuit 3 of the variable pole type variable speed AC motor 1 to be rotated. A signature S' in which the contact piece 7 of the contact 6 contacts the normally open contact 6 and closes.

Ｓ〃の給紙中は、低速巻線回路３に通電され、可変ボニ
ル式変速交流モータ１は低速回転するととになる。During the feeding of paper S, the low-speed winding circuit 3 is energized, and the variable speed AC motor 1 rotates at a low speed.

従って、折丁Ｓ′又はＳ〃は、送りローラＤ。Therefore, the signature S' or S〃 is sent to the feed roller D.

とはない。Moreover, the variable pole type variable speed AC motor 1 has a middle plate S3.
Or, it rotates at low speed only when feeding signatures S/, S// with endpaper S4, and normally rotates at high speed by high-speed winding circuit 2,
Since normal signatures S are fed at a fast speed, there is no possibility that the paper feeding to the thread binding machine will be delayed and the bookbinding capacity will be degraded.
