Abstract: A cloth clamping chuck includes a pair of chuck jaws and a driving process that rotates at least one of the pair of chuck jaws around an open-close axis x to change an opening degree of the pair of chuck jaws. The cloth clamping chuck has a catching portion which is arranged in a position out of an extension line of the chuck jaws, and in associated with the pulling operation of cloth, is caught in a portion of the cloth other than the portion clamped by the pair of chuck jaws to deflect a force applied to the clamped portion of the cloth toward a side along the open-close axis.

Abstract: An edge clamping device includes: a two-position holding device having a pair of holding chucks that hold two separate portions of a rectangular piece of cloth Y that are on or near the ridge of a fold, in a state where a right-angled triangular part S is revealed; an edge locating conveyor that is disposed under the two-position holding device and delivers the cloth Y having been released from the two-position holding device; clamping chucks disposed downstream of the edge locating conveyor in a delivery direction; and a position changing means that moves at least one of the two-position holding device, the edge locating conveyor, and the clamping chucks in a crosswise direction such that the right-angled triangular part S of the cloth Y held by the two-position holding device is located at a correct clamping position corresponding to the positions of the clamping chucks.

Abstract: An automatic cloth spreading machine, that keeps the number of pieces processed even in the event of failure in handling, includes a separating device for separating pieces of cloth one by one from a mass of cloth made of a plurality of pieces of cloth by cloth handling devices, an edge locating device for locating an edge of each of the pieces of cloth having been separated one by one, a spreading device for spreading the piece of cloth, the edge of which has been located, and a discharging device for discharging the piece of cloth having been spread to a subsequent step. The separating device includes multiple units of cloth handling devices that perform the same process, and the multiple units of cloth handling devices simultaneously perform at least one of single- or multiple-step processes of separating pieces of cloth one by one from the mass of cloth.

Abstract: A cloth clamping chuck and a cloth handling apparatus that can handle cloth so as to reduce falling of the cloth while avoiding damage to the cloth includes a pair of clamps, disposed facing each other, and an opening-closing means that moves the pair of clamps, relatively closer to or separated from each other. Each of the clamps has, at a leading end, a projecting part that projects toward the other opposite clamp. Each of surfaces of the projecting parts on a base end side of the clamps is formed either as a flat surface parallel to a facing direction of the pair of clamps or as an inclined surface inclining toward the above base end side while extending toward the other opposite projecting part.
