The invention is a flexible spool that serves as both yarn winder and storage vessel. The invention comes with an adapter made of plastic imbedded with a magnetic hex head attachment for use with a power drill or power screwdriver. When used, the invention protects yarn from tangles, knots, dust and debris and allows the user to knit with a continuous, easy feed of yarn from the beginning to the conclusion of a project.

A core (u1, u2) around which a nonaqueous electrolyte secondary battery separator is to be wound. A side surface of the core (u1, u2) has a depression (20). This makes it possible, in a case where cores (separator cores) are stored by being stacked while still wet after cleaning, to prevent damage to a core caused by a problem where cores stick together and an core lower in a stack falls when a core higher in the stack is removed.

An elliptical reel is provided. The elliptical reel can include one or more longitudinal support members about a longitudinal axis of the reel and on which hose can be wound for transport. A cross section of the longitudinal support members that is perpendicular to the longitudinal axis defines an outline that has an elliptical shape.

The present disclosure relates to an adhesive tape dispenser, for an adhesive tape roll having a core element, said dispenser essentially consisting of or comprising a carrier unit, in particular a housing, at least one grip member being connected, in particular via a connecting member, to the carrier unit for handling of the adhesive tape dispenser, a first bearing member essentially consisting of or comprising a rotatable bearing shaft arranged and adjusted for receiving the core element of an adhesive tape roll and for rotatably supporting said roll which is directly or indirectly arranged on and/or fastened to the carrier unit, a second bearing member essentially consisting of or comprising an, in particular non-rotatable, bearing shaft, which is directly or indirectly arranged on and/or fastened to the carrier unit, and a receiving member arranged and adjusted for receiving the core element of an adhesive tape roll that is rotatably arrangeable or supported on said second bearing shaft, an, in particular rotatable, applicator unit for attaching the adhesive tape to objects which is directly or indirectly joined to the carrier unit or which is integral with said carrier unit, at least one fastening means for a cutting blade, which is directly or indirectly joined to the carrier unit or which is integral with said carrier unit, and optionally a cutting blade held by said fastening means, wherein the grip member and applicator unit are located on opposite sides of the first or second bearing member and/or of the center of gravity of the dispenser. Furthermore the disclosure relates to an adhesive tape roll consisting of or comprising a core which comprises a receiving opening extending through the core in the longitudinal direction and an adhesive tape which is wound onto the core, wherein the core consists of or comprises a plastic material or a metal material, that the receiving opening which extends through the core has a polygonal cross-section, and that at least one stop is provided at an end of the receiving opening.

A core (u1, u2) around which a nonaqueous electrolyte secondary battery separator is to be wound. A side surface of the core (u1, u2) has a depression (20). This makes it possible, in a case where cores (separator cores) are stored by being stacked while still wet after cleaning, to prevent damage to a core caused by a problem where cores stick together and an core lower in a stack falls when a core higher in the stack is removed.

There is provided a new and improved reel member and a new and improved reel housing body that can suppress surface runout and accordingly suppress falling-off of an adhesive film, the reel member (1) including: a winding core section (2) around which an adhesive film is windable; and a flange section (3) provided on each of both end portions in a direction of a rotation axis of the winding core section, in which the winding core section and the flange section are provided separately from each other, and an amount of surface runout of the flange section is a value within a range of 0.2 mm. For example, a diameter of the winding core section and a diameter of the flange section may satisfy a predetermined mathematical formula.

A fabric roll up core for carrying rolls of sheet material such as ground covers or canopy sheet materials including netting materials, used in agriculture or horticulture, such as bird, insect, hail, shade, wind barrier netting materials, comprises a profile formed in an outer surface that assists in maintaining the sheet material on the fabric roll up core when rolling the sheet material onto the fabric roll up core and which may be effective to work with roll up drive means. The core may be formed in one piece or as multiple connected parts.

The present disclosure describes a cable reel. The cable reel may include a hollow core having a width; a first wall coupled to an end of the core and extending radially outward a distance from the core, the first wall comprising an opening aligned with the hollow core and at least one support member extending across the opening; and a second wall coupled to an opposing end of the core and extending radially outwardly a distance from the core, the second wall comprising an opening aligned with the hollow core; wherein the first wall and the second wall form a gap therebetween equal to the width of the core, the gap being configured to hold a length of excess cable wrapped around the core. Cable reel covers are also described.

A core (u1, u2) around which a nonaqueous electrolyte secondary battery separator is to be wound. A side surface of the core (u1, u2) has a depression (20). This makes it possible, in a case where cores (separator cores) are stored by being stacked while still wet after cleaning, to prevent damage to a core caused by a problem where cores stick together and an core lower in a stack falls when a core higher in the stack is removed.

Flat wound tape article with a flat core and tape wound around the core. The article is configured so that it can help protect the edges of the tape from adhering to dirt, dust, lint, etc. while maintaining a convenient shape for use.
