ABSTRACT:
The invention relates to a device for blowing or pushing products from a conveying member, to which end a number of spaced-apart members are employed, each being provided with a controllable air valve, or with sliding parts with a controllable driving mechanism which are mounted on an endless conveyor, belt or chain. Further, a control system has been provided in which detection members determine whether a product meets set quality requirements and when and by which member the approved products should be blown or pushed from the conveying member in such a way that the products are successively brought in predetermined arrangements or patterns.
