A stacking apparatus includes a conveyance unit, a stacking unit, and a separation member supply unit. The conveyance unit conveys sheets for circuit board. The stacking unit stacks the sheets. The separation member supply unit supplies a separation member to separate the stacked sheets at any position. The separation member supply unit places the separation member on the sheet in being conveyed.

A tape holder allows a person to hold and dispense masking tape easily when preparing for painting or performing other tape related activities. The tape holder may include a first portion that is capable of sliding into or out of a person's pants pocket while a second portion extends out of the pocket and holds one or more rolls of tape. Embodiments of the tape holder are economically made from a single length of bent rod. The tape holder allows the user to easily and quickly remove and replace a roll of masking tape.

A roller for supporting a material according to an embodiment of the present invention includes: a rotation shaft; a pipe having a space in which the rotation shaft is inserted; a deforming part that is connected to the rotation shaft and the pipe to deform the pipe; and a support part that is installed at the pipe to support the material. The deforming part includes: a thread portion provided on the rotation shaft; a nut part screwed to the thread portion; an inclined part that is disposed at an inner surface of the pipe and that is pressed by the nut part according to rotation of the rotation shaft; and a driving source that is connected to the rotation shaft to rotate the rotation shaft.

A continuous body folding device includes a conveying part having a moving surface that moves while suctioning and holding a first region of a continuous body, the conveying part conveying the continuous body in the longitudinal direction thereof; a first folding reference part in which a first endless belt, which moves in a first circulatory pathway along a first virtual plane including the moving surface, moves along a first reference segment adjacent to a virtual line of the continuous body in the same direction at the same speed as the moving surface; and first guiding members that are disposed along the first reference segment, contact a second region of the continuous body, and fold the continuous body along the virtual line and move the second region toward the first region so that the angle formed by the first and second regions becomes smaller as the continuous body is conveyed downstream.

An auto splicing apparatus of roll to roll feeding equipment includes first and second supply rolls in which component fabric of a single layer is wound in roll form and the component fabric is unwound from the first supply roll or the second supply roll along a predetermined transfer path including a pair of feeding rollers that are disposed at upper and lower sides, respectively, of the transfer path; a first cutter assembly that is installed to perform a first vertical rotation based on the transfer path between the first supply roll and the feeding roller and including a first fabric cutter and a first fabric absorption portion; and a second cutter assembly that is installed to perform a second vertical rotation based on the transfer path between the second supply roll and the feeding roller and including a second fabric cutter and a second fabric absorption portion.

A log saw for cutting convolutely wound logs of web material is disclosed. The log saw comprises a cutting blade operating in a cutting plane, a log saw clamp for the retention of a convolutely wound log of web material such that the convolutely wound log of web material extends in a log advancing path through to the cutting plane, and control means connected to the clamping device.

A log saw clamp for temporarily restraining a convolutely wound log of web material for a log saw is disclosed. The log saw clamp comprises a support structure having a first and second cam disposed therein, a pair of opposed first and second paddles, and a first and second linkage.

An array of finished products, each finished product in the array having a length relative error of less than 0.81% of a target length, H is disclosed.

An apparatus for manufacturing an electrode includes a plurality of guide rollers configured to transport an electrode plate. The apparatus detects a defect on the electrode plate being transported and cut, upon detecting the defect, the electrode plate at a starting part of the defect on the electrode plate to form a defective electrode plate. The apparatus also includes a first taping part connecting the defective electrode plate to a defective electrode roll. The apparatus cuts the electrode plate at an ending part of the defect on the electrode plate to form a normal electrode plate. The apparatus connects the normal electrode plate separated from the defective electrode plate in the second cutting part with a normal electrode roll. The apparatus winds and transports the normal electrode roll.

A method for winding a foil onto a winding core in order to form a coil and for unwinding the foil from the winding core. The foil comprises a support material of an electrode foil and an electrode foil, which has at least one active material, or a separator foil which are used as components of a battery cell. The winding core has a perforated circumferential surface with at least one opening. A coil is also provided that has at least a winding core and a foil which is wound on the winding core.
