Abstract
An apparatus for transporting a bundle of signatures moving continuously on a saddle chain to a working station includes an indexing chain moving with variable speed, and a clamping unit for keeping the bundle of signatures at a predetermined position on the indexing chain; a method of operating the apparatus; and a saddle binding machine incorporating the apparatus.
Claims18
An apparatus for transporting a bundle of signatures to a working station, comprising:
- an indexing chain moving according to a velocity profile with variable speed for transporting a bundle of signatures, the variable velocity profile including a stop;
- and
- a clamping unit for keeping the bundle of signatures at a predetermined position on said indexing chain.
An apparatus for transporting a bundle of signatures to a working station, comprising:
- an indexing chain moving with variable speed according to a periodic velocity profile during an operating mode for transporting a bundle of signatures;
- and
- a clamping unit for keeping the bundle of signatures at a predetermined position on said indexing chain.
A method for transporting a bundle of signatures, which comprises the steps of:
- feeding a bundle of signatures with continuous speed to a transfer point;
- transferring the bundle of signatures from the continuously moving saddle chain to an indexing chain;
- acting upon the bundle of signatures in order to keep the bundle of signatures in a definite position on the indexing chain;
- and
- moving the bundle of signatures on the indexing chain with a variable velocity profile to a working station, the variable velocity profile including a stop.
An apparatus for transporting a bundle of signatures to a working station, comprising:
- an indexing chain moving according to a velocity profile with variable speed for transporting a bundle of signatures;
- and
- a clamping unit for keeping the bundle of signatures at a predetermined position on said indexing chain, said clamping unit including at least one blowing device for blowing air to the bundle of signatures moving on said indexing chain, said at least one blowing device being located on at least one side of said indexing chain.
