Abstract: The present disclosure is directed to a core-roll that contains areas of anti-slip material and methods of making the core-roll. The core-roll has one or more anti-slip zones to allow a continuous paper web to be wound around the core without the need for additional physical restraint to keep the paper from shifting laterally along the core. In another embodiment, the disclosure describes a parent roll having an anti-slip core-roll that does not interfere with other operations that occur during converting.

Abstract: A motor-drive system for retractable covering having a headrail with a horizontally disposed roller supporting a top edge of a flexible fabric material includes an electric motor mounted within a housing and interconnected to the roller to selectively rotate the roller in opposite directions while minimizing noise created from vibrations within the system. This system includes motor mounts within the housing which separate and absorb vibrations of the motor within the housing and a drive disk of a moderately soft material, which is firm enough to transfer torque from the motor to the roller while being soft enough to absorb vibrations which would otherwise be transmitted from the motor to the roller. An interconnect mounting the drive disk to the drive shaft of the motor is also made of a third relatively soft material, which is harder than the drive disk to more ably transmit torque but soft enough so as not to unduly transmit noise.

Abstract: A spindle assembly for supporting a roll of paper product is disclosed with features that make the spindle versatile and useable for supporting paper product rolls in a plurality of styles of dispensers. The spindle assembly also includes features that assist in maintaining the supported paper rolls in a desired orientation, such as horizontally in a vertically oriented dispenser. This resists skewing of the rolls in the dispenser and facilitates the separation of the rolls as paper is used from a lower roll in a dispenser. Also, brake members are provided to engage the core of a supported roll of paper to slow down the rotation of the roll of paper when pulled upon by a user.

Abstract: A tubular core and associated method of manufacture are provided. The tubular core includes at least one inner ply and at least two plastic plies disposed thereon. The inner ply, which can be paper or plastic, has an inner surface upon which identifying indicia are printed, for example, before the tube is formed and while the inner ply is in a flat configuration. The first and second plastic plies are disposed on the inner ply and adhered so that the second plastic ply substantially covers the inner ply and the first plastic ply.

Abstract: Wide ply gaps are intentionally introduced into one or more plies in a radially intermediate zone of the wall of a spirally wound tube. Each ply having wide ply gaps is narrower than the width that would ordinarily be employed at a given spiral winding angle to achieve a butt joint between adjacent edges of consecutive turns of the ply, and the ply is wound at that given spiral winding angle in such a manner that gaps are defined between the adjacent edges of the consecutive turns of the ply. The wide ply gaps have the effect of increasing the compliance of the intermediate zone of the tube wall in the radial direction. Such increased radial compliance has been found to improve the ID stiffness of the tube relative to a tube constructed of the same materials but having no ply gaps in the intermediate zone.

Abstract: A winding tube has a tubular body and a removable and replaceable end ring. The end ring has opposite end faces that, according to one embodiment, each define at least two recesses that form start-up regions between the end ring and the tubular body for capturing yarn during a winding operation. The recesses are spaced apart from one another so as to allow the end ring to be easily mounted and secured to the tubular body, and allowing the end ring to be reversible in relation to the tubular body.

Abstract: A textile tube on which yarn is wound to form a pack comprises a body having a tubular body extending between opposed ends and an outer surface. At least one recessed score is defined proximate at least one end of the tube body. The recessed score has a substantially rectangular shape wherein the width of the recessed score is at least about five time the depth of the recessed score. As such, the recessed score provides more surface area for capturing yarn during a winding procedure. The recessed score also retains a substantially constant shape regardless of the moisture content of the tube, which is particularly advantageous when the tube body is formed of paperboard or other hydroscopic material.

Abstract: In a method for identifying the spinning position of cops, each cop is provided with an individual marker. The marker is read at the rewinding machine for determining the corresponding spinning position. The marker can e.g. consist of a bar code applied to an end of the cop's tube. With this system it becomes easy to attribute yarn parameters determined at the rewinding machine to individual spinning positions.

Abstract: Cylindrical bobbin cores have at least one radially oriented slot formed in at least one end thereof. The slot is sized and configured to mate with a radially extending blade associated with the drive head of the winder so as to achieve positive rotational drive therebetween. In view of this interconnection between the core and the drive head, significantly less spring pressure needs to be exerted against the core by the tail stock of the winder.

Abstract: The packing and stowing system of roll of automotive electric conductors is characterized by three independent sections that when adjusted, they form a back up cover that prevents the deformation of the cable during its winding and when it is being stowed. The sections are integrated by a cylindrical body that is opened when it is introduced in a bobbin, as guide and subjection element of the wound roll; and a post set on a base as support for the piling up of the packed rolls and the hoop of the platform.

Abstract: Magnetized bobbin cores are preferably wound with sewing thread to obtain sideless, pre-wound bobbins that have beneficial draw-off tensions, draw-off tension uniformity and overspin characteristics. The pre-wound sideless bobbins may thus be satisfactorily used in lock stitch sewing applications due to improved uniformity of draw-off tension combined with reduced bobbin overspin. The magnetized pre-wound sideless bobbins are also especially well suited for end-use sewing applications where automatic bobbin changing equipment is employed. Most preferably, the core is a cylinder formed of a thermoplastic or thermoset material in which magnetized particles are dispersed.
