Disclosed are a winding apparatus and a winding method, the winding apparatus includes: a winding needle, being configured to wind a winding material; a power supply assembly, being configured to be electrically coupled to the winding needle, so as to form current on an axis of the winding needle; and a magnet supply assembly, being configured to provide a magnetic field to the winding needle, a magnetic field direction intersecting the axis of the winding needle so that the winding needle generates an ampere force for resisting a deformation of the winding needle in the magnetic field when the winding material is wound. By the above method, the present application may reduce the deformation of the winding needle, reduce a defective rate of a winding product formed by the winding of the winding material, and improve quality of the winding product.

Layer constructions allow an adhesive tape to be wound to form a spool simply and with relatively uncomplicated apparatus. At least one layered construction comprises: an adhesive tape comprising at least one outer layer of pressure-sensitive adhesive; a release liner lying on the outer layer of pressure-sensitive adhesive; and an interliner lying on the side of the adhesive tape opposite the outer layer of pressure-sensitive adhesive, at least the side of the interliner facing away from the adhesive tape being adhesively furnished, wherein all layers of the layered construction finish substantially flush with respect to each other. At least one spool comprising a spool core and the at least one layered construction wound crosswise in a plurality of plies on said core, and a method for producing the at least one spool are also disclosed.

Disclosed is a sealing device for securing a packaging material. The sealing device for securing the packaging material comprises: a tape supply reel for supplying a sealing tape to which an RFID tag has been coupled; and a sealing part for sealing, with the sealing tape, an opening of a plastic packaging material holding a product, wherein the sealing part adheres the RFID tag, which is coupled to one end of the sealing tape having the length for one use, to an adhesive positioned on the other end portion of the sealing tape having the length for one use, wherein the RFID tag is broken by the adhesive strength with respect to the other end portion when the sealing tape sealing the plastic packaging material is torn.

A method of operating an off-line finishing device for fiber webs, in particular an off-line slitter-winder for winding fiber webs, wherein in operating the off-line device the running speed is automatically optimized to minimize cost of web breaks. The method considers the costs associated with a web break during unwinding in addition to the cost benefit of maximizing web unwind speed so as to maximize machine utilization. The method determines an optimal web break stopping time in a web break situation and how often a web break is predicted. Automatic optimization incorporates limitations including the maximum rotation speed of the parent roll, the maximum speed of the fiber web being unwound, the maximum positive torque which can be applied to the parent roll to accelerate the parent roll to a rotation rate which produces a desired web speed, and maximum braking torque.

A device for rolling up and unrolling a floating mat. The device of the invention includes an elongated hollow cylinder having a first end and a second end. The cylinder has an elongated slot formed therein which extends between the ends thereof. A mat retainer bar is positioned in the cylinder. One end of the mat extends inwardly through the slot in the cylinder and is secured to the mat retainer bar. End cap assemblies are secured to the ends of the cylinder and have a lever secured thereto. The mat may be rolled up on the cylinder or unrolled from the cylinder by rotating the cylinder by way of the levers. The levers may be pivotally moved with respect to the end cap assemblies so that they may be stowed in the end cap assemblies and the ends of the cylinder.
