Problems solved by technology

[0002] At the present stage, when producing products with safety threads, small-axis safety threads are used. The length of each small-axis safety thread is less than 7,800 meters, and the speed of the paper machine is 50 meters or more, resulting in very frequent thread changes, thereby reducing production costs. Therefore, there is an urgent need for a device that can conveniently realize the fast and accurate connection of the ends of the small shaft safety wire

Abstract

The invention discloses a line connection device of a safety line as well as a line connection method thereof, belonging to the technique field of a joint connection device of the safety line of anti-counterfeiting paper as well as the line connection method; the device comprises a frame on which a hot-pressing wheel moving up and down is arranged, and the hot-pressing wheel is positioned above the safety line, a guide wheel with a groove positioned under the hot-pressing wheel is also disposed on the frame, and the safety line passes through the upper end of the guide wheel groove, the breadth of the groove is larger than or equal to the thickness of the hot-pressing wheel, a safety line cutting device is arranged under the line-incoming side of the safety line for cutting off the safety line, and the line connection method utilizing the device is also provided; and the line connection device and method make the connection between end heads of the safety line simple and fast, and lay good groundwork for developing on-line connection devices.

Description

technical field [0001] The invention relates to a joint connection device and a connection method for a safety thread of anti-counterfeit paper. Background technique [0002] At the present stage, when producing products with safety threads, small-axis safety threads are used. The length of each small-axis safety thread is less than 7,800 meters, and the speed of the paper machine is 50 meters or more, resulting in very frequent thread changes, thereby reducing production costs. Therefore, there is an urgent need for a device that can conveniently realize the fast and accurate connection of the ends of the small shaft safety wire. Contents of the invention [0003] The object of the present invention is: the present invention provides a safety wire connection device that can quickly and accurately connect the ends of the safety wire. The device can realize fast wiring, reduce the loss of the safety thread when the shaft is changed, and improve the banknote paper yield. ...
