  • Publication number: 20130331250
    Abstract: Unattached elastic portions of an elasticised web are grasped and raised above a support surface for feeding the elasticised web. The raised portions are brought into contact with a knife blade that is positioned to protrude through the thickness of the raised elastic layer into free space so as to remain spaced from the support surface that is moving beneath the blade in a direction normal to the support surface. The raised elastic layer is held raised during trimming with the knife blade by an elevation element over which the elastic layer runs. A grasping device holds the unattached portion being cut in a taut state in the cross machine direction. The elastic layer thus spans across the elevation element and the grasping device. The knife blade extends through the thickness of the elastic layer along the spanned part of the elastic layer into free space.

  • Publication number: 20130216851
    Abstract: The method serves for producing network-like metal mats from metallic strip material, for which purpose the strip material is first provided with notches (2), running parallel to one another, for the forming of metal wires (1), by means of notching rollers. The notches (2) are thereby formed to such depths, depending on the material, that as far as possible no sliding fractures are formed. The notches (2) are interrupted by unnotched regions—the mutual spacing of which in the respective notch (2) determines the later possible mesh width—at least in such a way that they later form network nodes (4). The network nodes (4) are offset by approximately half a network node spacing in the respectively adjacent notches (2).

  • Patent number: 6430804
    Abstract: A balloon locking cup and securing system includes a cup having a latch interposed between a funnel shaped cup portion and a tube extension. The balloon cup is placed over a reciprocating needle hook rod in a securing system. The tail of the balloon is received by a hook at the end of the hook rod and a first pneumatic cylinder is actuated to pull the needle hook rod in such a manner as to pull the balloon into nesting engagement with the balloon cup. At the end of travel of the first pneumatic cylinder, a second pneumatic cylinder is automatically actuated, causing a knife blade to separate the end of the balloon tail just beneath the tubular member of the balloon cup assembly. The drawing of the balloon into the cup assembly actuates the latch which engages the balloon tail near the neck of the balloon and secures the balloon in the cup assembly.
