  • Patent number: 5753326
    Abstract: A method and apparatus is provided for forming clear shrinkable film material for use as labels on containers. A blend of general purpose polystryene and styrene-butadiene or styrene butyl acrylate is extruded from an annular extruder die orifice to form a frustoconical tube which is stretched before cooling air is applied to form a clear film that has machine direction orientation and cross direction orientation that can be used as a shrinkable label on containers. As the tube is extruded, it is shielded from cooling air which is applied downstream from the extruder die orifice. The apparatus shields the hot annular extruded material adjacent the die orifice. The air is supplied downstream from an annular air orifice which is designed with a taper that allows ambient air to be freely drawn in and eliminates what would be a negative pressure zone immediately downstream of the air orifice while eliminating air turbulence and improving cooling.

  • Patent number: 5732745
    Abstract: A thermoplastic tube for in-field storage or packaging of bales of agricultural products is disclosed. The tube combines high puncture resistance with an exceptional stretchability, elasticity and good slip properties. The circumference of the tube can be expanded by at least 15% without tearing when stretched in the transverse direction. The tube also shows no substantial permanent deformation 2 hours after being so stretched for a period of time not exceeding 30 minutes and released. Before feeding a bale, the tube is stretched radially to facilitate the insertion and accommodate bales larger than original diameter of the tube. When regaining the original size, the tube wraps up tightly the bales reducing the amount of air trapped in the tube. Since the tube can be enlarged to a variable extent, it may accommodate bales of different shapes and sizes.

  • Patent number: 5712011
    Abstract: A tug-resistant unit in which the first and second relatively inextensible members overlap one another. A shear-thickening composition having dilatant flow characteristics is disposed between the first and the second inextensible members. The composition provides a variable resistance to linear movement of the second inextensible member relative to the first inextensible member as a function of the shear forces exerted upon the dilatant fluid. The inextensible members may be enclosed within an extensible enclosure to form an elastic strap. Alternatively, one inextensible member may form a portion of the enclosure while the second inextensible member is disposed within the strap so as to overlap the first inextensible portion of the enclosure. The strap provides low resistance to slowly-varying tensile forces and high resistance to rapidly-changing tensile forces, thereby moderating the velocity of relative motion between the ends.
