Abstract

An apparatus for producing an adhesive-bound printed product comprises an endlessly circulating transport system where a transport clamp holds a clamped-in printed product with the aid of a first adjusting mechanism that generates a first movement component while the printed product circulates through the apparatus. To favorably influence an opening and/or closing movement depending on the printed product), the apparatus comprises a second adjusting mechanism to be selectively activated and to generate in an activated position a second movement component that acts upon a swivel arm. The second movement component is oriented counter to an upward movement of the control arm induced by the first movement component. The counter-oriented movement components are compensated via a second mechanical spring which supports the swivel arm relative to the control arm.

First claim

What is claimed is:

1. An apparatus for producing an adhesive-bound printed product, comprising:
a transport system including a plurality of transport clamps each for clamping therein and conveying a printed product, wherein the transport clamps are arranged to have a circulating movement endlessly along a cam track, wherein each transport clamp comprises:
a swivel arm and an adjustable clamping element attached to the swivel arm that can be movable via the swivel arm back and forth to place the adjustable clamping element in an open position and a closed position for clamping the printed product;
a spring box, a first mechanical spring arranged in the spring box, and a tension rod arranged in the spring box;
a first adjusting mechanism to generate a first movement component;
a control arm having a first end connected via the spring box to the swivel arm and a second end connected to the first adjusting mechanism to transmit the first movement component generated by the first adjusting mechanism via the spring box to the swivel arm, wherein the first movement component is oriented in an upward direction so that the adjustable clamping element is swiveled from the closed position to the open position, wherein the first mechanical spring exerts in the closed position of the clamping element a clamping force onto the clamped in printed product via the tension rod and the swivel arm, and wherein the tension rod in the closed position of the clamping element compensates for different thicknesses of the clamped-in printed product via a compression or extension of the first mechanical spring;
a second adjusting mechanism which is selectively activatable and which, in an activated position, generates a second movement component directed to the swivel arm in a direction counter to an upwardly directed movement of the control arm induced by the first movement component; and
a second mechanical spring arranged to support the swivel arm against the control arm to compensate the counter directed first and second movement components.

2. The apparatus according to claim 1 , wherein the second mechanical spring is arranged in the spring box, and the second adjusting mechanism when activated is connected via the swivel arm to a first end of the second mechanical spring and that the second mechanical spring is connected at a second end via a support plate of the tension rod to the first mechanical spring.

3. The apparatus according to claim 2 , wherein the tension rod, at an end facing away from the support plate is fixedly connected via a rotating joint to the swivel arm, the rotating joint is installed on a joint head which is rigidly connected to the swivel arm a position of which changes relative to the spring box during relative movements between the control arm and the swivel arm, the first mechanical spring when installed is kept in place by a perforated disk that is secured with its outer edge to a wall of the spring box, on a side facing the joint head, the tension rod furthermore is inserted through a hole in the perforated disk, the second mechanical spring on a side facing the joint head is supported on a sleeve which extends through the hole of the perforated disk and is installed movable along the tension rod, the sleeve in an inactivated position of the second adjusting mechanism is held by the second mechanical spring so as to be supported on an inside edge of the perforated disk and in the activated position of the second adjusting mechanism is lifted by the joint head from the inside edge of the perforated disk and is pressed counter to the spring force of the second mechanical spring into the inside space of the spring box.

4. The apparatus according to claim 1 , wherein the mechanical springs travel along differing force paths.

5. The apparatus according to claim 1 , wherein the second adjusting mechanism comprises a sliding track which extends only over a partial section of the circulating movement of the transport clamps and cooperates with a control roller which is rigidly connected to the swivel arm.

6. The apparatus according to claim 5 , wherein the sliding track of the second adjusting mechanism is mounted in a holding device so as to be adjustable, the control roller connected to the swivel arms of the transport clamps passes the sliding track without making contact in at least one of the adjusted positions.

7. The apparatus according to claim 6 , wherein the holding device) is provided with a motorized drive which can move the second adjusting mechanism.

8. The apparatus according to claim 7 , wherein the motorized drive is connected to an electronic remote control.

9. The apparatus according to claim 8 , characterized in that wherein the sliding track includes a running surface comprised of a shock-resistant plastic material.
