Abstract: PURPOSE:To obtain a cylindrical article in an extremely easy and certain manner by a method wherein a sheet not substantially stretched in the longitudinal direction thereof but stretchable in the lateral direction thereof is fixed at four substantial corner parts and conc. load is applied to the central part of the sheet to plastically deform said sheet. CONSTITUTION:When a sheet S is plastically deformed by stretching operation, the tensile force thereof in the longitudinal direction is large ant, therefore, the stretching stress in the longitudinal direction is within an elastic range and the sheet S is almost not stretched. Further, since the tensile force in the lateral direction of the sheet S is small, the stretching stress in the lateral direction exceeds the elastic range to generate monoaxial stretching wherein the sheet S is stretched in the lateral direction and a cylindrical article 2 is molded. When a molding member 8 is raised upwardly (in the direction shown by an arrow) in such a state that the sheet S is fixed at four substantial corner parts to apply concn. load to the central part of the sheet S accurately with respect to four corner parts from the space between press members 7, 7, the molding member 8 protrudes upwardly in a state covered with the sheet S and, at this time, the sheet S is stretched to be plastically deformed and molded as the cylindrical article 2. After the sheet S is molded as the cylindrical article 3, a ring 3 is mounted to the base end part of the cylindrical article 2 and the residual sheet S is treated to obtain an applicator A.

Abstract: PURPOSE:To enable the insertion of an absorbing body at a specified position in a vagina smoothly eliminating a friction resistance of the absorbing body with the wall of the vagina while allowing the removing of a housing cylinder smoothly. CONSTITUTION:In a tampon 1 for housing an absorbing body 2 into a housing cylinder 6, the housing cylinder 6 comprises a flexible cylindrical sheet part 61 and a rigid cylindrical part 62 provided successively to the flexible cylindrical sheet part 61 and a first takeoff device 63 and a second takeoff device 64 are connected to the tip part of the flexible cylindrical sheet part 61 separately while being formed longer than the housing cylinder 6. The first takeoff device 63 and the second takeoff device 64 have a coupling point 65 at which they are connected together partly while the length thereof is different from each other to the connection of the tip part from the coupling point 65.

Abstract: PURPOSE:To stretch a sheet without generating creases by clamping all over edges of both sides of the sheet by means of a couple of clamping sections in stretching, sliding the sheet between a couple of clamping sections gradually and stretching in the width direction. CONSTITUTION:When a raw fabric sheet 10 reaches a stretching device, an edge of one side of the raw fabric sheet 10 is clamped by a large diameter pulley 31 of a first clamping section 30 and a V-belt 33 of a small diameter pulley 32, and simultaneously an edge of the other side of the raw fabric sheet 10 is clamped by a middle diameter pulley 41 and a V-belt 43 of a small diameter pulley 42 in a second clamping section 40. While the raw fabric sheet 10 is moved downstream side through the first clamping section 30 and the second clamping section 40 as respective pullies rotate, both edges of the raw fabric sheet 10 are integrally clamped in the arc shape by the large diameter pulley 31, the V-belt 33, the middle diameter pulley 41 and the V-belt 43, and the distance between said both clamping sections of arc-shape is stretched gradually by the difference of curvatures of the large diameter pulley 31 and the middle diameter pulley 41 in the width direction of raw fabric sheet 10.

Abstract: PURPOSE:To facilitate the insertion of an absorptive article, etc., into a body and, simultaneously, to unite it compact at the time of rejecting it by using an ethylene tetrafluoride resin unbaked sheet composed of a first member formed of a longitudinal axis direction with a small stretch and a second part formed of a lateral axis direction with a large stretch. CONSTITUTION:When a member 8 for formation is made to advance upward and a concentrated load is given between pressing members 7 and 7, the member 8 for formation is made to advance upward under a condition covered with a sheet S, the sheet S is extendingly stretched, it is plastic-deformed, it is formed as a housing cylinder 3, a ring 6 is fitted to the base edge of the housing cylinder 3, and then, an applicator is obtained. For the ethylene tetrafluoride resin unbaked sheet formed as the housing cylinder 3, the first part with a small stretch, namely, a molecule orientation degree in a lengthwise direction is 70% or above at the time of the formation, and the second part with e large stretch, namely, the molecule orientation degree in a direction eight-angled to an A direction is 50% or above. At the time of inserting the applicator, a holding part 6 is held, the applicator is inserted as it is, then, it is locked at a large diameter part, an inserting edge position is automatically decided, and since the housing part 3 is flexible, has a small resistance and stretches not longitudinally but laterally, the insertion is easy.

Abstract: PURPOSE:To provide an applicator easy to insert and made as small as possible at the time of disposal by forming a receiving part wherein anisotropic high extensibility is provided and a vertical axis direction low in extensibility is set to a longitudinal direction and a horizontal axis direction high in extensibility is set to a radius direction. CONSTITUTION:A filter or sheet S optimum for molding this receiving cylinder 3 is formed, for example, by forming the tetrafluoroethylen non-baked sheet S used in the receiving cylinder 3 into a long sheet by extrusion or molding and drying said long sheet. When a molding member 9 is pushed upwardly in such a state that the sheet 3 is fixed at substantial corner parts at four places and load is accurately concentrated to the central part with respect to four corner parts between press members 8, 8, said sheet S is stretched to be plastically deformed and molded as the receiving cylinder (receiving part) 3. A ring 6 is mounted to the base end part of said receiving cylinder 3 and the residual sheet S is treated to obtain a required applicator.
