摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a gap between a barrel portion of a bobbin and the inside of a layer consisting of a linear material wound thereon by producing a less change in barrel size with the change of an ambient temperature of the bobbin on which the linear material such as optical fiber is wound, thus preventing the collapse of regular winding of the linear material due to the occurrence of the gap and smoothing the delivery of the linear material from the bobbin. SOLUTION: A linear material wound bobbin which has a cylindrical barrel portion 2 and two disc collars 1 provided at both ends of the barrel portion 2 comprises a separation part 2a formed in a circumferential portion of the barrel portion 2 along the axial direction so that force acts in the direction of increasing the barrel size of the barrel portion 2 by the energization of a spring laid in the separation part 2a when the barrel size is reduced with the reduction of a gap in the separation part 2a. Further, a fixing means such as a fixing pin is provided for fixing the barrel size at a constant value which is less than the maximum value.

摘要： PROBLEM TO BE SOLVED: To unreel yarn from press bobbins smoothly after dyeing by preventing such dragged movement of the yarn at the ends of the press bobbins as results from the difference between the overall length of the press bobbins and the width of traverses. SOLUTION: The press bobbin has annular elements 2 at both ends, a plurality of vertical frames 4 extending between the end annular elements 2 in annular arrangement, a plurality of annular lateral frames extending between and parallel to the annular elements 2, and small compressible vertical pieces 5, 6 and 8 crossing the annular lateral frames. Two levels 3b of the annular lateral frames from each annular element 2 have a smaller diameter than the others, so that in this region the vertical frames 4 and small vertical pieces 5, 6 and 8 have an external surface projecting from that of the annular lateral frames 3b and that a yarn wound can slide on them without difficulty. Auxiliary ribs 9 lie between the two upper and lower annular lateral frames 3b to provide resistance to compression.

摘要： PROBLEM TO BE SOLVED: To provide a roll body such as a waterproof sheet or the like, which will not be collapsably deformed at all even if it is loaded sidewise, and it is not bulk large after usage, besides being easily settable and disposable, and also its manufacturing method. SOLUTION: A sheetlike material 11 such as a waterproof sheet or the like is molded into being the specified width and thickness, and then this sheetllike material 11 is rollingly wound up into a roll body 1 in keeping a hollow core part left behind, and a bag body consisting of a synthetic resin or synthetic rubber is inserted into this hollow core part and gas is filled up in this bag body and sealed, thereby forming this bag body into a hollow tubular body 21 which is held in a pressed state to the sheetlike material 11. Thickness of the synthetic resin or rubber should be set to a range from 0.01 to 0.5 mm, and Mullen bursting strength should be not less than 0.15 kg/cm2. In this connection, a gas blowing port 41 is installed in one end of the hollow tubular body 21.

摘要： PROBLEM TO BE SOLVED: To take up and accumulate sheet materials such as a photosensitive material and image receiving material and also separate a core easily from the taken-up sheet material without requiring trouble and labor. SOLUTION: A core member 132 of a core 130 is composed of a first main body 132A, a second main body 132B, and a third main body 132C which are divided into 3 parts along the axial direction. A projection 150 formed on each main body can be put into a cam notch 146 of a cam 140. For this reason, when the cam 140 rotates, the inner peripheral wall of the cam notch 146 is engaged with the projection 150, so that all main bodies are mutually pulled nearer in an inward direction of the diameter and consequently the outside diameter of the core 130 is reduced. Therefore, the core 130 can be easily removed from a sheet material, after the sheet material is taken up in stara around the periphery of the core 130.

摘要： PROBLEM TO BE SOLVED: To satisfactorily remove a take-up core from a take-up product or a take-up piece, by tubularly bending a leaf spring in the cross direction, piling the leaf spring in the double wall form at least over a constant angle range from its both side edges, and taking up web material or others on a take-up core. SOLUTION: A leaf spring 3 is tubularly bent in the cross direction. One leaf spring 3 is bent in the double wall form over whole circumference from its both side edges 4, and is piled up. When a web material 1 is taken-up on a take-up core, a take-up core 2 receives its take-up pressure. In this case, because bent parts 5a, 5b of the leaf spring 3 reinforce the take-up core 2, the take-up core 2 bears the take-up pressure of the web material 1 and is not damaged. Furthermore, take-up pressure of the web material 1 acts to the bent parts 5a, 5b of the leaf spring 3, the bent parts 5a, 5b of the leaf spring 3 is elastically transformed and compressed due to the take-up pressure, and the web material 1 is taken-up in this condition. Therefore, the web material 1 can be tightly taken-up.
