Abstract

The needle is attached to one end of the electromagnet armature, which is acted on by a return leaf spring. Pref. the plate is profiled and the microelectromagnets controlled by a controllable electronic pulse generator. Specif. the micro-perforations are made in food-packaging film to avoid condensn. which could adversely affect keeping qualities. The foodstuff may be a dairy prod. bakery prod. fruit or vegetable.
