Abstract: In automatic preparation of flexible, disposable packing containers for materials such as eggs or fruits during intermittent transportation along a straight path of travel of each packing container, an opener cord is wound up and tied about the joint between receptacle and cover of the packing container while provisionally deforming, making use of the flexibility, the packing container so that the joint should assume an arcuate construction, and removal of deformation brings about tight winding-up of the joint so that pulling of the cord in a sealed packing container by users should enable easy opening of the packing container through breakage of the joint.

Abstract: An automatic leasing machine for a warp beam on which a warp delivered from the warp beam is grouped into separate warp sheets of different colors, and warps from a warp sheet in turn are subsequently separated from the sheet, passed through a gap between a pair of warp leasing cords which alternate positions once per one warp passing, and fixed by means of bonding tapes. The foregoing operation is repeated cyclically in a fully automatic fashion for all warps in the warp sheet in accordance with a given stripe design of the yarn dyed fancy fabric to be woven.
