摘要： Ultrasonic sealing apparatus, including at least one anvil and at least one transducer opposed to the anvil to transmit ultrasonic energy to a workpiece clamped between them, is disclosed. The anvil and sealing horn each are reciprocated between an open position allowing a carton to pass and a closed position for sealing a closure. A biasing element is connected between the anvil or the horn and its drive to define the sealing pressure developed between the anvil and the horn. The biasing force can be adjusted without stopping the machine, by using an externally applied pneumatic force. The anvil has a backing element, a facing member, a body, and a resilient pad separating the body from the facing member. The backing element has a curved front surface facing the transducer. The back surface of the anvil pad is curved similarly to and bears against the curved front surface of the backing element. A fastener is provided for selectively fixing the anvil pad and the backing element together or allowing the anvil pad to shift along the curved surface of the backing element for aligning the anvil with respect to the transducer. The apparatus may also include cooling fluid passages within the facing member and extending through the anvil body and the resilient pad for carrying fluid from the source of cooling fluid through the facing member of the anvil. A method for aligning the anvils and transducers of a ultrasonic sealing apparatus as described above is also disclosed.

摘要： A filling system of a packaging machine is set forth that reduces the mixing of product and air during the filling of the container with a flowable material such as low fat milk. The fill pipe of the filling system has an elliptical cross-section which provides for a reduced velocity of the flowable material entering the container while allowing for an increased production time of the packaging machine. The fill system is especially adopted to fill containers having a rectangular cross-section. Connected to the fill pipe is a nozzle with flaps designed to substantially conform and engage with the sidewalls of a container. When the flaps are urged to an open position, the mixing of air and product is inhibited as the flowable material is dispensed into the container through the nozzle and as a moving mechanism is operated to relatively move the container and nozzle from a first to a second position. The fill pipe has an elongate body, an inlet end and an outlet end. The inlet end is in flow communication with the fill pump and may have a circular cross-section. The outlet end is in flow communication with the nozzle and has an elliptical cross-section. The cross-section of the elongate body gradually transforms from a circular cross-section at the inlet end to an elliptical cross-section at the outlet end.
摘要翻译：提出了一种包装机的填充系统，其在用诸如低脂牛奶的可流动材料填充容器期间减少产品和空气的混合。填充系统的填充管具有椭圆形横截面，其提供进入容器的可流动材料的降低的速度，同时允许包装机的生产时间增加。填充系统特别适用于填充具有矩形横截面的容器。连接到填充管的喷嘴是具有折板的喷嘴，其设计成基本上配合并与容器的侧壁接合。当翼片被推动到打开位置时，当可流动材料通过喷嘴分配到容器中时，空气和产品的混合被抑制，并且当移动机构被操作以将容器和喷嘴从第一到第二位置。填充管具有细长主体，入口端和出口端。入口端与填充泵流体连通，并且可以具有圆形横截面。出口端与喷嘴流动连通，具有椭圆形截面。细长体的横截面逐渐从入口端的圆形横截面变换到出口端的椭圆形横截面。
