Abstract
A machine for the adhesive binding of sets of pages comprises a control device with: a sensor to sense the thickness of the set of pages placed on the carriage and held gripped between the jaws thereof, said sensor being arranged to provide a signal representative of the thickness of the set of pages which is so gripped, and a regulating unit for modifying the speed of the motor means in response to an output signal from the sensor.
Claims15
A method of operating the motor means of an adhesive binding machine for sets of pages, said motor means being adapted to cause reciprocation along a guide path of a carriage comprising a gripper formed by a moving jaw and fixed jaw, in such a manner as to position the carriage successively at a loading station, a routing station, a gluing station and an encasing station, characterized by the following steps:
- a detecting by means of a sensor the thickness of a set of pages after input into the machine, while the set of pages is being held between the jaws of the carriage, and
- controlling the motor means in order to modify its speed in a manner inversely proportional to the thickness of the set of pages being detected.
A device for operating a binding machine adapted to adhesively bind sets of pages, comprising a carriage having a gripper formed by a moving and a stationary jaw, a motor means adapted to reciprocate the carriage along a guide path extending in a first direction from cooperating relationship with a loading station for charging the carriage with a set of pages, to a routing station for routing a back face of such set of pages, then to a gluing station for the application of adhesive to the said back face and thence to an encasing station for the application of a cover to the set of pages and pressing such cover onto the back of the set for bonding the cover thereto, characterized in that the device comprises:
- a sensor to sense the thickness of the set of pages placed on the carriage and held gripped between the jaws thereof, said sensor being arranged to provide a signal representative of the thickness of the set of pages which is so gripped, and
- a regulating unit for modifying the speed of the motor means in response to an output signal from the sensor.
