The Winckler machine (first quarter of 20th c.) worked on the same principles as the famous Boucher machine (1898). It used a pneumatic system to blow air and a mechanical system to shape the bottle and then remove it from the mould. Four people (gatherer, presser, turning-out boy, and a carrying-in boy) and two moulds (rougher and finisher) were required to make a bottle. This machine could comply with the standards regarding size and capacity, and lower production costs. A team could produce on average 3,000–3,500 bottles in eight hours, while the free-blower could only manage 500. Training times for the workers were also reduced. Nevertheless the machine was only ‘semi-automatic’ because the glass had still to be gathered from the furnace by hand.er.
