    Abstract: A breathable girth former for a packaging machine for bathroom tissue and kitchen toweling rolls wherein the entrance funnel (preformer) has two halves resiliently mounted to conform to the product dimension most likely to jam in the downstream girth former. The funnel halves movement is transmitted to the girth tube former halves by a mechanical linkage to provide the same spacing as in the funnel.

    Abstract: A sealing apparatus includes a plurality of pairs of upper and lower sealing die assemblies which travel around upper and lower pairs of oval tracks. Each of the oval tracks includes upper and lower horizontal portions and front and rear curved end portions. Each pair of die assemblies is driven independently of the other pairs. Each of the die assemblies includes a pair of carriages which are supported by the tracks and a sealing die which extends between the carriages. A pair of bogie arms are pivotally mounted on each of the carriages, and a pair of rollers which are rotatably mounted on each bogie arm ride on one of the tracks. The sealing apparatus seals a series of products in a plastic film as the products and film are advanced along a horizontal path which extends between the upper tracks and between the lower tracks. A first pair of upper and lower sealing dies engage the film behind a first product and in front of a second product as the first dies move along the curved rear end portions of the tracks. The first dies push the film against the rear of the first product and seal and sever the film as the first dies move along the horizontal portion of the tracks. A second pair of dies engage the film behind the second product and repeat the sealing and severing operation.

    Abstract translation: 密封装置包括多对上下密封模组件,它们围绕上下椭圆形轨道对运动。 每个椭圆形轨道包括上部和下部水平部分以及前部和后部弯曲的端部。 每对模具组件独立于其他对驱动。 每个模具组件包括由轨道支撑的一对托架和在托架之间延伸的密封模具。 一对转向架臂可枢转地安装在每个托架上,一对滚子可旋转地安装在每个转向架臂上的一个轨道上。密封装置将塑料膜中的一系列产品密封成产品和 胶片沿着在上轨道之间和下轨道之间延伸的水平路径前进。 当第一模具沿着轨道的弯曲的后端部分移动时,第一对上,下密封模具接合第一产品后面的膜并在第二产品的前面。 第一个模具将胶片推向第一个产品的后部,并且当第一个模具沿着轨道的水平部分移动时,密封并切割胶片。 第二对模具与第二产品后面的胶片接合,并重复密封和切断操作。
