Abstract: A production apparatus comprises a step-wise driven conveyor adapted to receive articles to be subjected to different operations. Along the conveyor operative devices are arranged for carrying out the different operations to which the articles are to be subjected. The operative devices having comparatively short operation periods are stationarily arranged along the conveyor, whereas at least two operative devices having comparatively long operation periods, are movably arranged along the conveyor so as to follow the conveyor while the conveyor makes at least one step and then to be moved one such step opposite to the direction of movement of the conveyor. By such doubling of the operative device or devices having long operation periods, an increased capacity of the production apparatus is achieved. The production apparatus can be used in producing ice cream coronets.
