Abstract

Stapling devices, which form staples from a staple wire transported from supply rolls, are arranged in a stapling apparatus. The supply rolls are associated with a threading-in device which is mounted displaceably on the stapling apparatus. Transport mechanisms as well as feed-in and guide mechanisms are associated with each supply roll. Flexible guide tubes connect the threading-in device to the respective stapling device. The threading-in device can be moved into a position pulled out of the stapling apparatus device, in which the supply rolls can easily be inserted. The leading end of the wire is pushed, in simple and conveniently visible fashion, between a transport roller pair by way of a guide element and a funnel-shaped feed-in tube. From there the leading end of the wire is pushed by manual drive through the flexible guide tube to a transport mechanism on the stapling device until, upon passing by a switch, the end of the manual threading-in operation, and the fact that the staple wire is ready for automatic continued transport, are indicated. The threading-in device is pushed into the stapling apparatus after completion of the threading-in operation.
