摘要： Captive leader web loading and unloading apparatus for automatically capturing the free end of a take-up leader extending along the web transport path, at the conclusion of the supply web rewind operation. A capture device automatically decouples a supply leader from the captive leader without requiring the application of auxiliary motions to the supply reel after rewind. The device includes a bistable mechanism having a first stable configuration for cooperating with the take-up leader such that the take-up leader is captured along the web transport path, and a second stable configuration for releasing the take-up leader when coupled to the supply leader. The bistable mechanism is actuated to assume its first stable configuration, by the take-up leader during decoupling from the supply leader. After automatic coupling of the take-up leader and the supply leader, the take-up leader actuates the bistable mechanism to assume its second stable configuration.

摘要： An apparatus for performing relative to an elongate information carrier initially located in a casing a predetermined function outside of the casing has a mechanism for moving a length of the elongate information carrier relative to the casing. A drive for the moving mechanism is provided and a device for transmitting driving power to the moving mechanism is connected between the drive and the moving mechanism. A control device is coupled to the transmitting device for controlling the moving mechanism. An apparatus in accordance with a further aspect of the invention also has a mechanism for moving a length of the elongate information carrier out of the casing. This apparatus further includes a mechanism operatively associated with the moving mechanism for locking the casing of the elongate information carrier in position against manual removal preparatory to movement of the information carrier length out of the casing.

摘要： Automatic web threading apparatus providing an unobstructed and continuous temporary threading path between web supply and takeup stations. A threading track having integral stripper means is normally positioned completely out of the web transport path, and during threading operation the track is caused to move to a position for receiving the web, or a ''''relatively stiff'''' leader attached thereto, when supplied by the supply station and for guiding the supplied web or leader to the takeup station.
