<Prior Art> When forming a fastening annular groove at both ends of a fiber drum, conventionally, an annular strip plate for reinforcing an annular groove is first press-fitted into openings at both ends of the fiber drum, and then one end is The end portion of the fiber drum, in which the strip plate is fitted, is inserted between the drive roller in which the recessed groove is formed in the annular groove forming machine of the table and the pressing roller which is fitted in this recessed groove. The fastening annular groove is formed at one end, and then the fiber drum is inverted to form the fastening annular groove at the other end in the same procedure as described above.

<Problems to be Solved by the Invention> When forming an annular groove with the above-mentioned conventional apparatus, after processing one opening end of the fiber drum, the fiber drum must be inverted to process the other opening end. However, there was a problem that it was difficult to do and productivity was poor.

Therefore, for example, as described in Japanese Patent Laid-Open No. 54-14886, a rotary head having a processing device that rotates and moves along both ends of a cylindrical fiber drum having a fixed central portion is provided. There is also a machine in which both ends of the fiber drum are machined by rotating the machine while rotating the machine. In these machines, however, the opening diameter of the square fiber drum is machined because the rotating diameter of the rotary head is perfect. In addition, the rotary head must be replaced each time the open end of a fiber drum with a different diameter is to be machined, which is troublesome and the device must be stopped during replacement. Therefore, there is also a problem that the moving efficiency also decreases.

The present invention has been proposed in view of the above problems, and it is possible to form the fastening annular groove in the opening at both ends at a time without reversing the fiber drum, and to continuously and easily end both ends regardless of the size of the square or the diameter. The purpose of the present invention is to make it possible to form an annular fastening groove in the opening.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention has an annular groove forming machine that sandwiches a fiber drum transport rail and arranges an annular groove forming machine so that groove forming portions face each other. A drive roller that is rotationally driven by drive means is provided in the forming and processing section so that it can slide back and forth, and a groove is formed on the outer peripheral surface of the drive roller, and a pressure roller that fits into the groove is used as the drive roller. The fiber drum is provided so that it can be moved toward and away from the driving roller from the outside of the end of the supported fiber drum, and is sandwiched and held between the pressing roller and the driving roller by the pressing force of the pressing roller and the driving force of the driving roller. It is characterized in that the fastening annular groove is formed while rotating the end portion of.

<Operation> When the fiber drum is conveyed to the groove forming portion by the fiber drum conveying rail, the drive roller projects and loosely fits on both ends of the fiber drum.

Next, when the drive roller is driven to rotate together with the fiber drum by the drive means, the pressing roller moves to the drive roller side and comes into pressure contact therewith, and when fitted into the recessed groove, the fastening annular rings are respectively attached to the outer peripheries of both ends of the fiber drum. The groove is formed.

In the case of a rectangular fiber drum, the fastening annular groove is formed while rotating the end of the fiber drum sandwiched and held between the pressure roller and the driving roller by the pressing force of the pressing roller and the driving force of the driving roller. The fastening annular groove can be formed on the outer circumference of both ends.

Further, even if the diameters of the cylindrical fiber drums are different, since the fiber drums rotate, the fastening annular grooves can be formed on the outer circumferences of both ends.

<Example> Hereinafter, an example of the present invention is described based on a drawing.

As shown in FIG. 1, an apparatus 1 for forming an annular groove for fastening a fiber drum according to the present invention includes a conveying rail 3 provided above a base 2 and an annular groove provided so as to face each other with the rail 3 interposed therebetween.

And a groove forming processed portion 8 provided in the portion.

The drive means 7 includes an electric motor 9 disposed inside the lower portion of the casing 5 and the casing 5 near the rotary drive shaft 6.
The transmission shaft 10 is rotatably supported by the belt transmission mechanism 12 that transmits the rotation of the electric motor 9 to the transmission shaft 10 and the gear reduction device 13 that reduces the rotation of the transmission shaft 10 and transmits the rotation to the rotation drive shaft 6. Become.

The groove forming portion 8 is configured such that a relatively large-diameter drive roller 14 attached to the tip end portion of the rotary drive shaft 6 and a lift cylinder 15 above the drive roller 14 can contact and separate from the upper surface of the drive roller 14. And two pressing rollers 17 rotatably supported on a triangular bracket 16.

Further, the drive roller 14 is engraved on the peripheral surface portion 14a thereof with a single annular groove 18 which is formed in a round shape in a side view, and when the pressing roller 17 descends, the peripheral edge portion thereof forms the annular groove 18. It is designed to fit.

Although not shown, the electric motor 9 and the elevating cylinder 15 are operated in conjunction with each other by the control device of the control panel.

Further, in FIGS. 2 and 3, reference numeral 20 is a fiber drum.
