Abstract: A method for operating an elongated element through a full length of a bended duct being bended over a major part of its length, the method comprising the steps consisting in: introducing a liquid into the bended duct and maintaining predetermined flow and pressure conditions of the liquid into the bended duct, compensating a friction between the bended duct and an end of the elongated element being bended by the bended duct, by locally applying a predetermined axial effort to the end of the elongated element.

Abstract: A collection and compacting apparatus for cardboard refuse such as flat pieces of cardboard and broken down or collapsed cardboard boxes and a uniquely shaped coil of flexible lashing for use with the apparatus for bundling the cardboard refuse. The apparatus, preferably wall mounted, includes a rigid support frame which defines a stationary upright surface and a lower horizontal support surface extending from a lower portion or margin of the stationary surface. A movable platen defines a flat cardboard refuse crushing surface and is pivotally connected at a lower end thereof to the horizontal support surface about an axis spaced from and parallel to the stationary surface.

Abstract: An apparatus and method for shaping shoulders of a cylindrical yarn package by rotating the package about its central axis and applying pressure to both shoulders of the package simultaneously. One apparatus embodiment includes drive rolls for rotating the package and rotatable elongated shaping elements mounted for movement into and out of engagement with the shoulders of the package. The positioning of the rollers with respect to the point of contact on the package shoulders is important to the operation of the apparatus.

Abstract: In a winding wound in a figure-8 configuration, such as a universal winding which is known in the textile industry, the endforms of a spindle on which the winding is wound each respectively include openings enabling the projection therethrough of collapsing members such that the ends of the winding may be compressed to a substantially flat plane with the innermost winding. The mandrel is formed in two movable sections such that the two sections collapse towards one another with application of the compression force applied to each of the endforms.

Abstract: In a coil of material wound in a series of figure-8 coils with the crossovers progressing around the package but being interrupted at one point to provide a radial opening into the axial opening of the coil, in order to produce a thick-walled coil the material is first wound in a normal way with varying gains in order to produce a set of dense inner layers, while the outer layers are wound without variation in the gain to produce a honeycomb structure. The honeycomb section is of greater width (axially of the package) than the inner layers. A plurality of pins slidably mounted on a strip are pushed into the outside of the package through the openings in the honeycomb, whereafter the outer layers are compressed axially while retaining the pins within the outer layers. The pins permit payoff of the outer layers without danger of their collapsing and thereby forming kinks or twists within the package.
