    摘要： Hollow articles of thermoplastics, especially bottles, are made from tubular blanks by heating the ends thereof and press molding first their bottom and neck portion. Then the preformed blanks are heated around their center portion and are transferred into blow molds for inflating them to the final shape. The machine consists of a first rotary table with preheating and press molding means, a second rotary table with final heating means and a third rotary table with blow molds. The rotary tables are connected by transfer stations so that the blanks can be automatically transmitted and conveyed around all tables. The high throughput allows installation before racking plants.

    摘要： A method for blow molding containers and the like articles from thermoplastic parisons. The parisons are heated in two stages, i.e., in a pre-heating oven to a uniform temperature less than the blow molding temperature and by infra red radiation to a final blow molding temperature which, preferably, is non-uniform along the length of the parison. The non-uniform heating is accomplished by moving the parison axially through an annular infra red radiator at varying rates of speed. Since the degree of heating is directly proportional to the time of exposure to the radiation, a variable temperature profile can be imparted to the parison by means of a simple speed program. Such a variable temperature profile results in controlled wall thickness distribution during blow molding, and the final container is of enhanced strength and of lower weight.

    摘要： A power driven cultivator which comprises frames and a plurality of rollers which are rotatably mounted in the frames. A driving motor is operatively connected with the rollers and supported by the frames. The rollers are equipped with ribs and bearing means are secured to the frame for the rotatable mounting of the rollers. The latter are coupled together in pairs by means of chain wheels and chains to provide a rear pair of rollers and a front pair of rollers. The rear pair of the rollers is pulled and disposed in the frame at a gap behind two of the front drivable pair of rollers. A platform is disposed between the front pair of rollers supporting the driving motor and coupling means, chain wheels and a chain are operatively connected with the driving motor.
