    • The aim of the invention is to transfer plastic bags (1) to a collector (4) in a bag producing machine. To this end, devices are known comprising an impeller (6) consisting of a central hollow shaft (7) which is connected to a rotational drive (9) and a low pressure source. A plurality of impellers (8) are fixed to the hollow shaft (7) in a radially interspaced manner. The inside of said impellers is embodied as a suction channel (10) and a longitudinal side of the impellers has a suction surface (16) comprising a plurality of suction openings (11). In order to improve the suction force on the impellers (8), the suction surface (16) of the impellers (8) contains suction openings (11) having a diameter of between 3 mm and 12 mm, preferably between 6 mm and 9 mm. The open part formed by the suction openings (11), on the entire suction surface (16), amounts to more than 3 %, preferably more than 5 %. According to another embodiment, the impellers (8) of the suction channel (10) have a reduced cross-section in the region below the suction surface (16).
    • 塑料袋(1)与(6)组成,其连接到旋转驱动器(9)和连接到真空源的中央空心轴(7)的叶轮传送到集电极的制袋机(4)是已知的装置。 在中空轴(7)的多个叶片臂(8)被附连到径向突出,其被设计为在所述内吸气管(10)和上一个纵向侧(16)有多个抽吸开口(11)的抽吸表面上。 为了提高对翼臂的抽吸力(8),其直径为3至12毫米之间毫米,优选6毫米和9毫米的翼臂(8)吸入口(11)的吸附面(16)。 所形成的总吸附面(16)的开口部分的抽吸开口(11)的是超过3%,优选大于5%。 根据另一解决方案中,在吸附面(16)下面的区域中的翼状臂(8)的吸入通道(10),以一个减小的横截面。

    • This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to transferring discrete parts to a continuous web, whether paper, film, composite, or the like. Specifically, the invention relates to methods and apparatus for taking discrete parts from a source in a taking zone, optionally taking the discrete parts as components of a continuous web, onto a transport head on a transfer assembly, severing the discrete parts from the continuous web if received as part of a continuous web, rotating the transfer assembly about a first axis and correspondingly rotating the transport head about a second axis radial to the first axis, to thereby present the discrete parts to a receiver in a transfer zone, and transferring the discrete parts to the receiver in the transfer zone. The invention includes using a roughened taking section on the transport head, interacting with textured surface on the discrete parts, to hold the discrete parts to the transport head, with optional use of suction through the transport head to assist in holding the discrete parts to the transport head. Novel apparatus is included for delivering suction to and through rotating slip rings.
