Problems solved by technology

[0004] But, because the above-mentioned conveying roller and cutting roller that absorb, receive hygienic articles are circumscribed while rotating, so the structure of above-mentioned prior art is not suitable for high-speed operation.
In addition, since the cutting roller only performs suction, the suction hole is easily blocked
This will reduce the operating rate of the device

no. 1 Embodiment

[0043] Figure 1~ image 3 shows the first embodiment.

[0044]In FIG. 1 , a fabric 3 , which is a continuous sheet, is fed between a backup roll 1 and a cutting roll 2 . After the fabric 3 passes between the cutter roll 2 and the back-up roll 1 , a predetermined portion (ejection portion) 31 of the fabric 3 is molded to form through holes 30 at a predetermined pitch.

[0045] The cutter roll 2 is arranged at a position circumscribing the backup roll 1 . The aforementioned cutting roller 2 has several blades 20 . The aforementioned blade 20 is used to eject the aforementioned ejector part 31 so that it is connected into a ring shape. In this embodiment, the larger-diameter flange portion 23 formed on the cutter roll 2 circumscribes the backup roll 1 . The flange portion 23 stabilizes the rotation of the cutting roller 2 and protects the aforementioned blade 20 .

[0046] Both ends of the cutting roller 2 are provided with first and second fixing members (adjacent members) 6...

no. 2 Embodiment

[0069] Figure 4 and Figure 5 Shown is the second embodiment.

[0070] As shown in FIG. 4 , the device can also form through holes 30 on discontinuous sheets 3 . In this case, as Figure 5 As shown, a holding portion 10 for holding a sheet 3 is provided on the supporting roller. The holding portion 10 can be constituted by an arm or the like that presses the sheet 3 against the surface of the backup roll 1 . Generally, the holding part 10 has a plurality of air holes 12, and, like the cutting roller 2, has a structure having a function of absorbing air.

[0071] In this case, it is necessary to determine the positions of the holding portion 10 and the blade 20 and the phase relationship of the backup roller 1 and the cutting roller 2 . In addition, transfer rollers 13 and 14 may also be used as supply and conveyance means of the web 3 .

[0072] The other structures are the same as those of the first embodiment, and the same or corresponding parts are indicated by the sam...

Abstract

The invention forms a through hole (30) on the fabric (3) between the supporting roll (1) and the annular blade (20) of the cutting roll (2). The present invention absorbs the ejection part (31) in the ring inner area (21) of the cutting roller (2), ejects air from the air holes (22) of the aforementioned inner ring area (21), and simultaneously removes the mold ejection part (31 ) is sucked into the pipeline (80) and discharged.

Description

technical field [0001] The present invention relates to a cutting and removing device and a cutting and removing method for forming through-holes of a predetermined shape in a single-layer or laminated sheet. Background technique [0002] One of the known methods of forming through holes in a sheet is a method called die cutting using a cutting roll (eg, JP-A-8-71999 and JP-A-11-188698). The aforementioned cutter roll ejects the sheet between the support roll and the back-up roll. However, in the aforementioned prior art, there is no mention of a method of discarding the ejector portion (die-cut portion). If the ejector part is discarded improperly, the ejector part will be clogged with the dies of the cutting rollers, etc., so frequent cleaning is necessary, reducing the operating rate of the device. [0003] In addition, JP-A-8-52696 discloses a device for molding sanitary products from an original negative sheet. In this prior art, the molded sanitary articles are plac...
