本考案は表面に起毛を有する合成樹脂シートを

置（例えば実公昭45−33038号公報）においては
次の如き欠点があつた。 For example, the suede-like texture of natural leather,
There is a need for a sheet that can be molded from a synthetic resin to give it a certain appearance, and is currently known as a raised resin sheet. When forming such a raised resin sheet, a large number of needle holes are inserted at close intervals on the circumference of the roll.
Moreover, a raised resin sheet with a uniformly formed mold roll is used to obtain a raised resin sheet with a surface that looks like fluff, but conventional manufacturing equipment for the mold roll (for example, Japanese Utility Model Publication No. 45-33038) had the following drawbacks.
即ち、上記製造装置は軟質金属製型ロール材を

面より約１mmの深さに打込まれるように設定して
いる。 That is, the above-mentioned manufacturing device continuously and gently rotates a soft metal mold roll material, and moves the needle group up and down by a crank-operated drive mechanism, so that the surface of the mold roll material and the tip of the needle group are moved up and down. The spacing is set so that the tip of the needle group at the bottom dead center is driven to a depth of about 1 mm from the surface of the mold roll material.

で、正円の穴ができない。また針尖端の折損を防
止するために、型ロール材を軟質金属で形成して
いるが、この軟質金属の場合型ロールの耐久性が
低い等の問題点があつた。 However, in such a device, since the operation of repeatedly driving needles into the mold roll material that is continuously rotated is performed, the tip of the needle driven into the mold roll material is affected by the rotational force of the mold roll material. If the needle is twisted, the tip of the needle may be broken, or the opening of the hole formed in the mold roll material may be distorted into an elliptical shape, making it impossible to form a perfectly circular hole. In addition, in order to prevent the tip of the needle from breaking, the mold roll material is made of a soft metal, but this soft metal has problems such as low durability of the mold roll.
本考案はかかる問題点を解消するためになされ

A movable table 4 is threadedly supported on the screw rod 1 and is movable only in the axial direction of the screw rod by rotation of the screw rod 1, and a cylinder 5 is attached to the movable table 4. At the lower end of the movable shaft 7 of the cylinder 5, a needle group 8 formed by bundling a large number of needles is attached. Reference numeral 9 denotes a mold roll material from which a mold roll is to be formed, and this mold roll material 9 is rotatably supported by a pedestal 10 and a drive shaft 13 driven by a pulse motor 11 and a speed reducer 12. It is now connected to The pulse motors 3 and 11 mentioned above are intermittently driven to rotate by output pulses from a control circuit (not shown).

ものである。 The configuration of this embodiment has been described above, and its operation will now be described. By intermittently supplying pressurized fluid to the cylinder 5, the needle group 8 is reciprocated up and down. This reciprocating range, that is, the mold roll material 9
The distance between the surface of the needle and the tip of the needle group is set so that the tip of the needle group at the bottom dead center is driven to a depth of about 1 mm from the surface of the mold roll material. Therefore, by intermittently driving the pulse motor 3 while reciprocating the cylinder 5, the needle group 8 is sequentially shifted laterally while forming a hole in the surface of the mold roll material 9 with its tip. That is, when the needle group 8 is driven into the mold roll material, the pulse motor 3 is not driven, and when the needle group 8 is pulled up, the pulse motor operates intermittently to advance the needle group 8 by one step. be. When holes are thus drilled from one end of the mold roll material to the other, the pulse motor 11 rotates by one pitch of the needle group 8, and then, as described above, the intermittent operation of the pulse motor 3 and the reciprocating motion of the cylinder 5 cause the mold to be drilled. By drilling holes in the roll material 9 in the generatrix direction and repeating the above operations, closely spaced needle holes are uniformly formed over the entire circumferential surface of the mold roll material 9.

加工を施すことができる。 In the above embodiment, the pulse motor 3 is operated intermittently to sequentially move the needle group 8 in the generatrix direction of the mold roll material 9 for punching. The punching may be performed sequentially in the circumferential direction of the pulse motor 9, and further, by appropriately setting the operations of the pulse motor 3 and the pulse motor 11 by pulse control,
The peripheral surface of the mold roll material 9 can be perforated in an appropriate pattern.

ることもできる効果がある。 As described above, in the device of the present invention, the needle group 8
When the needle group 8 is driven into the mold roll material 9, the movement of the needle group 8 or the rotation of the mold roll material 9 is temporarily stopped, so there is no need to force the needle group to break when driving the needle group. As a result, breakage of the needle is eliminated, and the hole shape drilled in the mold roll material 9 becomes a perfect circle corresponding to the needle shape, so that the desired mold roll can be manufactured.
Furthermore, since the needles are not strained as described above, the mold roll material 9 can be made of a relatively hard material, which has the effect of making it possible to manufacture a durable mold roll.
