Title: Method and device for depositing a roving of textile fibres
Inventor: OEHY PETER
IPC: B65H54/80
Filed: 1982-03-17
Granted: 1985-08-29
Abstract: The textile fiber sliver is deposited in cans in the form of cycloid-type loops. During deposition, the sliver is delivered via a rotating funnel gear wheel into a rotating can. In addition, the mutual distance between the axes of rotation of the gear wheel and can is varied by laterally displacing the can. Also, the rotational speed of the can is varied during operation so that when the distance between the axes of rotation of the wheel and can is at a minimum, the can rotates at a maximum speed. Likewise, when the distance between the axes of rotation is at a maximum, the can rotates at a minimum rotational speed.

Abstract: A machine for bending an elongated workpiece extending along a longitudinal axis has a housing and a holder on the housing for retaining the workpiece with its axis nondisplaceable relative to the housing and for advancing the workpiece in a feed direction parallel to the axis. A support defining a mandrel axis transverse to the longitudinal axis and spaced transversely therefrom is displaceable with the mandrel axis on the housing transverse to the longitudinal workpiece axis. A mandrel carried directly on the support is formed with an arcuate groove centered on the mandrel axis. This mandrel carries an inner jaw forming a continuation of the groove and is rotatable therewith on the support about the mandrel axis. An arm mounted directly on the support pivotal about the mandrel axis carries an outer jaw generally complementary to the inner jaw and a guide carried directly on the housing mainly upstream of the mandrel has a guide groove confronting the groove of the mandrel and centered on the longitudinal workpiece axis. A jaw actuator can displace the outer jaw on the arm radially of the mandrel axis. A guide actuator can displace the guide on the housing transversely of the feed direction and independently of the support. A support actuator displaces the support and the jaws and mandrel carried thereby transverse to the direction and independently of the guide. A pivot actuator pivots the support about the mandrel axis to bend the workpiece between the jaws and the guide.

Abstract: §) A microapertured polymeric web exhibiting a substantially uniform soft and silky tactile impression on at least one of its surfaces. In a preferred embodiment the present invention relates to webs exhibiting a fine scale pattern of discrete surface aberrations, each of said surface aperrations having its amplitude oriented substantially perpendicular to the surface in which said surface aberration originates. At least one tiny aperture (microaperture) is provided substantially coincidental with the maximum amplitude of each surface aberration. The discontinuity created by the aperture at the peak of each of the surface aberrations substantially reduces the resistance to both compression and shear of each individual surface aberration. In addition the volcano-like edges formed at the periphery of each microaperture are typically in the form of thin, irregularly shaped petals which not only reduce the total contact area with the user's skin, but which are also easily deflected when re'ative movement with the user's skin occurs. Microapertured webs of the present invention are also relatively quiet when subjected to movement, making them particularly suitable for use as topsheets and/or backsheets in disposable absorbent structures such as adult incontinent briefs.
