Abstract: A packing structure includes a housing and a cushion portion. The housing includes a bottom plate and a sidewall while the cushion portion is disposed on the bottom plate of the housing. A groove and a jaw portion are formed on an end portion of the cushion portion. The jaw portion is located on a side of the groove facing the sidewall and extends away from the bottom plate. A first tongue plate is formed on the sidewall of the housing and bends inward. A free end of the first tongue plate enters the groove through an opening of the groove, wherein a backside of the jaw portion interferes with the first tongue plate to restrict the first tongue plate from leaving the groove. When the cushion portion is under external forces and moves away from the bottom plate, the first tongue plate will support a bottom inner surface within the groove to restrict a displacement of the cushion portion away from the bottom plate.

Abstract: A roller mounted onto a fabric winding machine to roll up fabric aims to solve the shortcomings of the conventional rollers that tend to cause fabric skewing during fabric rolling and are difficult to remove due to a lengthy structure. The roller of the invention has an outer diameter gradually enlarged towards two ends, and includes a first half roller and a second half roller that have respectively a first positioning portion and a second positioning portion at one end corresponding and fastenable to each other. The greater diameters at two ends allow the fabric to be rolled up on the roller without skewing. The two pieces design of the roller makes each piece shorter and removing from a bundle of rolled up fabric easier. The roller thus formed can facilitate fabric rolling and removal thereof.

Abstract: A fabric collection structure for a fabric cutting apparatus splits fabric and has a driving means. The fabric collection structure includes a fabric rolling rod and a fabric pressing means. The fabric pressing means has a fabric spread rod and a fabric pressing rod. During fabric collection, the driving means drives the fabric rolling rod, fabric spread rod and fabric pressing rod to rotate. The fabric split by the fabric cutting apparatus is flatly unfolded by the fabric spread rod and driven by the fabric pressing rod to be rolled on the fabric rolling rod, and is pressed by the fabric pressing rod. The fabric pressing rod is lifted by increasing thickness of the fabric rolled on the fabric rolling rod. The fabric rolling rod rolls the fabric at a fixed location. The fabric pressing means presses the fabric to control the density and a uniform fabric density is achieved.
