Abstract
A conveying device having individually controllable grippers conveys the printed products in the conveying direction to a straightening station where the printed products are aligned. Subsequently, for opening, the folded printed products are fed to an opening device with their open edge leading and are then conveyed further to a transfer region, which is spaced apart from the opening device, for depositing on the rests. The separation of the different functions, i.e. the alignment, the opening and the depositing of the printed products allows simple setting to different formats of the printed products to be processed. Between the opening device and the transfer region, the open printed products are held open by a holding-open device.
Claims23
A method for opening folded printed products and depositing them on a saddle-type rest the method comprising the steps of:
- holding the printed products at their fold by means of individually controllable grippers of a conveying device;
- moving the controllable grippers in a conveying direction to an opening device;
- opening the folded printed products at the opening device;
- conveying the opened printed product from the opening device to a transfer region, the transfer region being spaced apart from the opening device;
- holding the printed products open with holding-open means separate from the opening device as they are conveyed from the opening device to the transfer region;
- and
- depositing each of the open printed products astride a saddle-type rest in the transfer region by opening the grippers.
An apparatus for opening folded printed products and depositing them on a saddle-type rest, comprising:
- a conveying device having individually controllable grippers which are moved in a conveying direction, and are arranged one after the other, for gripping a printed product at its fold in each case and feeding the printed product to a transfer region, where it can be deposited astride a rest by opening of the gripper;
- an opening device for opening the folded printed products prior to depositing to define a leading part and a trailing part of the printed product, wherein the opening device is mounted at a distance upstream of the transfer region;
- holding-open means to act on both parts of the printed products which have been separate from one another by means of the opening device for holding the printed products open between the opening device and the transfer region;
- and
- the holding-open means being separate from the opening device.

- holding-open means to act on both parts of the printed products which have been separate from one another by means of the opening device for holding the printed products open between the opening device and the transfer region, the holding-open means having an active run comprising a beginning section and an end section, the beginning section being disposed by the opening device and the end section being disposed in the transfer region;
- and
- a straightening station mounted at a distance, upstream of the opening device for aligning the printed products relative to the grippers during at least partial opening of the grippers.
