본 발명은 조출(繰出)기구의 간헐적인 작동에 의해 웨브로울(web roll)로부터 공급되는 웨브를 일정한 길이 만큼씩 풀어내면서, 이 풀어내는 중간에 조출기구의 간헐적인 작동과 연동하면서 작동하여 웨브로울로부터 웨브를 인출시키는 예비조출기구를 설치한 웨브공급장치에 관한 것이다.The present invention operates by interlocking with the intermittent operation of the feeding mechanism while releasing the web supplied from the web roll by a certain length by the intermittent operation of the feeding mechanism by a predetermined length. The web supply apparatus provided with the preliminary | feeding-out mechanism which draws out a web from the web.

종래에는 이 종류의 웨브공급장치로서, 예컨대, 일본국특개소 62-158629호 공보에 기재되어 있듯이, 웨브로울로부터 튜우브 성형체에 이르기까지의 조출과정에서, 예비조출롤로와, 이 예비조출롤러의 아래쪽에서 자유자재로 움직일 수 있도록 부착되는 텐션레버로 된 예비조출기구를 설치하며, 이 텐션레버에 회전축이 지지되어 자유자재로 회전할 수 있는 복수개의 텐션롤러와, 이들 텐션롤러와 각각 마주보는 상태로 설치된 복수개의 가이드롤러에 웨브를 걸므로써, 텐션레버나 텐션롤러의 중량으로 웨브에 일정한 장력을 주면서, 동시에 조출기구의 간헐적인 작동에 의해, 웨브를 간헐적으로 일정길이만큼식 풀어내어, 텐션레버가 요동했을 때에, 이것을 검출기로 감지하여, 예비조출롤러를 회전시켜서 웨브로울로부터 웨브를 인출하여 텐션레버를 초기상태로 되돌리며, 그 결과 웨브로울로부터 웨브가 인출되는 힘이 경감되며, 웨브는 항상 일정한 장력이 작용되어 팽팽하게 걸려있게 되는 것이다.Conventionally, as a web supply apparatus of this kind, for example, as described in Japanese Patent Laid-Open No. 62-158629, in the feeding process from the web roll to the tubular molded body, the pre-feeding roller and the lower side of the pre-feeding roller are used. And a preliminary feeding mechanism made of a tension lever attached to move freely in the cage, and a plurality of tension rollers rotatably supported by a rotating shaft and facing the tension rollers, respectively. By hooking the web to a plurality of guide rollers installed, the web is fixed by a tension lever or a tension roller, and at the same time, the intermittent operation of the feeding mechanism makes the web intermittently released by a certain length. When shaking, this is detected by a detector, the pre-feed roller is rotated, the web is pulled out of the web roll, and the tension lever is Turning back to the state machine, and as a result is a force that the web is drawn out from the web roll reduction, the web is always taut so that a predetermined tension is hanging operation.

그런데, 이와 같은 종래의 웨브공급장치에서는, 웨브의 간헐적인 조출속도에 대응하는 속도로 텐션레버가 요동하므로, 특히, 웨브가 고속으로 간헐조출되며, 텐션레버의 요동시에 그 텐션레버와 텐션롤러의 중량에 의한 관성이 작용하여 필요각도 이상으로 요동되고, 이것에 따라 조출된 웨브에서도 지연이 발생되며, 웨브가 그 조출에 따라 종동하는 복수개의 텐션롤러와 가이드롤러를 개재하여 걸쳐있으므로, 특히 웨브가 고속으로 간헐조출되면, 이들 다수의 종동롤러의 회전관성에 의해 웨브가 필요이상으로 조출되어서 되돌아가는 현상이 발생되고, 이 결과, 웨브의 장력이 전혀 작용되지 않아 웨브가 느슨해지기 쉬워서 웨브가 조출되는 방향과 직교하는 폭방향으로 어긋남이 발생하거나 웨브에 일정간격으로 레지마이크를 붙여서, 그 레지마아크를 기준으로 위치를 결정하여 웨브의 모양을 맞추려하는 경우에는 위치결정의 정확도가 저하하는 문제가 있다.By the way, in such a conventional web feeder, the tension lever oscillates at a speed corresponding to the intermittent feeding speed of the web. In particular, the web is intermittently fed out at high speed, and the tension lever and the tension roller Inertia by weight acts and swings more than necessary angle, and delay is generated even in the web fed out, and the web is interposed through a plurality of tension rollers and guide rollers that follow the feeding. Intermittent feeding at high speed causes the web to be fed more than necessary due to the rotational inertia of these driven rollers, resulting in the phenomenon that the web does not work at all and the web tends to come loose and the web is fed. The deviation occurs in the width direction orthogonal to the direction, or by applying a resist microphone to the web at regular intervals. To determine the position relative to the case to align the shape of the web there is a problem that the accuracy of the positioning lowered.

더우기, 웨브는 다수의 종동롤러에 의해 극단적으로 구부려지는 부분이 많으므로, 웨브의 재질에 씨실의 올이 있어서 딱딱한 경우에는, 종동롤러에의 감김이 나쁘고, 웨브 전체에 균일한 장력이 작용되지 않는 문제가 있으며, 또 다수의 종동롤러에 웨브를 걸어주는 작업이 귀찮다고 하는 문제도 있다.Moreover, since the web has many parts which are extremely bent by a large number of driven rollers, if the web material has a weft of thread, the winding of the driven roller is bad and the uniform tension is not applied to the entire web. There is a problem, and there is also a problem that it is cumbersome to hang the web on many driven rollers.

본 발명은 이러한 종래의 문제점을 감안하여, 관성체를 개재하지 않고 극단적으로 구부리는 부분을 적게 하면서 웨브를 걸며, 웨브의 폭방향으로 이동하지 않도록 항상 일정하게 장력을 작용시키는 것을 목적으로 한다.In view of such a conventional problem, an object of the present invention is to provide a constant tension so as not to move in the width direction of the web by hanging the web while reducing an extremely bent portion without interposing an inertial body.

전기한 과제를 해결하기 위하여 본 발명이 제안한 기술적 방법은, 예비조출기구의 하류에서 웨브를 흡인하여 U자 형상으로 처지도록하는 흡인기구를 설치하고 이 U자 형상으로 처진 웨브의 처짐량이 변화에 따라서 예비조출기구의 작동을 제어하며, 또, U자 형상 웨브의 폭방향에서, 양쪽 가장자리와 각가 맞닿는 가이드면을 서로 마주보도록하여 설치한 것을 특징으로 하는 것이다.In order to solve the above problems, the technical method proposed by the present invention is provided with a suction mechanism which sucks the web downstream of the preliminary injection mechanism and sags in a U shape, and the deflection amount of the web sagging in the U shape is changed according to the change. It controls the operation | movement of a preliminary | feeding-out mechanism, and is provided so that the guide surface which abuts both edges and an angle may face each other in the width direction of a U-shaped web.

그리고, 전기한 흡인기구는, 한쪽끝은 웨브가 들어갈 수 있는 개방부가 형성되어 있고, 다른쪽 끝은 흡인구를 형성한 상자형상의 흡기실과, 개방부로부터 흡기실내로 들어가는 U자 형상 웨브의 처짐량을 검출하는 검출기로 구성되어 있으며, 이 검출기에서의 출력에 따라 예비조출기구의 작동을 제어하여, U자 형상 웨브의 처짐량을 일정하게 유지하며, 흡기실내에서 서로 마주보는 가이드면의 간격을 웨브의 폭과 거의 같은 길이로 하여 형성하는 것이 바람직하다. 또, 전기한 웨브공급장치는 웨브로울로부터 공급되는 웨브를 튜우브성형체를 개재하여 통형상으로 형성한후, 횡접합기를 작동시켜서 웨브를 폭방향으로 접합하여 자루를 형성하며, 그 자루내에 피포장물을 충전시키는 제대충전포장기(製袋充轉包裝耭)가 설치된 웨브공급장치이며 조출기구를 튜우브 성형체의 하류쪽에 설치하여도 좋다.The suction device described above has an opening portion through which a web can enter one end, and a deflection amount of a box-shaped intake chamber in which the other end has a suction port, and a U-shaped web entering the intake chamber from the opening portion. The detector is configured to control the operation of the preliminary feeding mechanism in accordance with the output from the detector, to keep the deflection of the U-shaped web constant, and to maintain the distance between the guide surfaces facing each other in the intake chamber. It is preferable to form the length substantially the same as the width. In addition, the web supply apparatus described above forms a web supplied from the web roll through a tubular molded body in a tubular shape, and then operates a transverse splicer to join the web in the width direction to form a bag. A web feeder is provided with a umbilical packing machine for filling the gas. A feeding mechanism may be provided downstream of the tubular molded body.

본 발명은 전기한 기술적 방법에 의하면, 흡인기구를 작동시켜서 웨브를 흡인하여 U자 형상으로 처지게 하므로써 웨브에 일정한 장력을 작용시키고, 웨브의 간헐조출에 따라 U자 형상의 웨브가 서로 마주보는 가이드면에 의해 폭방향으로의 위치가 결정되면서 인출되며, U자 형상 웨브의 처짐량의 변화에 따라 예비조출기구의 작동을 제어하여 U자 형상 웨브의 처짐량을 일정하게 유지하는 것이다.According to the above-described technical method, the suction mechanism is operated to draw a web to sag into a U-shape to apply a constant tension to the web, and the U-shaped webs face each other according to the intermittent feeding of the web. It is drawn out while the position in the width direction is determined by the surface, and the deflection amount of the U-shaped web is kept constant by controlling the operation of the preliminary feeding mechanism in accordance with the change of the deflection amount of the U-shaped web.

다음에, 본 발명의 한 실시예를 도면에 의거하여 설명한다.Next, an embodiment of the present invention will be described with reference to the drawings.

본 실시예에는 제 1 도에 표시하듯이, 웨브로울(A)로부터 제대충전포장기(D)의 튜우브 성형체(D1)에 이르기까지의 조출과정(B)에서, 그 중간에 흡기실(2)과 검출기(3)로 구성된 흡인기구(C)를 설치하며, 튜우브성형체(D1)의 하류에는 조출기구(E)로서의 조출벨트를 제대충전포장기(D)의 제대용 원통체(D2)의 외면과 마주보도록 하여 설치하여, 이 조출기구(E)의 간헐적 작동에 의해, 예컨대, 조출롤러등으로 구성된 예비조출기구(1)의 웨브(W)인출방향으로 웨브(W)를 일정길이만큼씩 풀어내는 것이다.In this embodiment, as shown in FIG. 1 , in the feeding process (B) from the web blower (A) to the tubular molded body (D 1 ) of the umbilical packing machine (D), the intake chamber (2) is located in the middle thereof. ) and the detector 3, the suction mechanism (a substitute cylinder of C) the installation and tubing probe molded article (D 1) downstream, the feeding mechanism (E properly filled packing machine (D a feeding belt as a)) of the body consisting of (D 2 ) Is installed to face the outer surface, and the web W is fixed to the web W in the drawing direction of the preliminary feeding mechanism 1 composed of a feeding roller or the like by intermittent operation of the feeding mechanism E, for example. It is to solve as much.

흡기실(2)은 복수개의 평판을 사용하여 세로방향으로 길이가 긴 상자형상으로 만들어지며, 그 윗쪽은 개방된 상태이다. 이 개방부(2a)에서 조출방향과 직교하는 방향으로 있는 한쌍의 개방부(2a)의 테두리를 각각 테두리의 종단면도가 원호형상이 되도록 형성하며, 웨브를 V자 형상으로 하여 양쪽 원호형상의 테두리(2a1)(2a1)의 사이에 넣은후, 이들 양쪽 원호형상 테두리(2a1)(2a1)에 웨브(W)를 걸친다. 흡기실(2)의 아래에는 흡인구(2b)를 설치하며, 흡기실(2)의 내부는 이 흡인구(b)를 개재하여 흡기실(2)의 외부에 설치되는 흡인유량이 큰 시로코팬(siroco fan)등의 흡인원(2c)과 연결된다.The intake chamber 2 is made into a box shape long in the longitudinal direction by using a plurality of flat plates, and the upper side thereof is open. In the opening portion 2a, the edges of the pair of opening portions 2a in the direction orthogonal to the feeding direction are formed so that the longitudinal cross-sectional view of the edges is an arc shape. (2a 1) was placed in between (2a 1), it spans the web (W) on each side thereof a circular arc-shaped rim (2a 1) (2a 1) . A suction port 2b is provided below the intake chamber 2, and the inside of the intake chamber 2 has a large suction flow rate that is provided outside the intake chamber 2 via the suction port b. It is connected to suction sources 2c such as (siroco fan).

이 흡인구(2b)의 주위에는 흡기실(2)의 안쪽으로 스폰지등의 통기체(2b1)를 부착하고, 그 윗면에는 망(2b2)를 설치하여 흡인구(2b)의 주위에는 흡기실(2)의 안으로 웨브(W)가 흡인되는 것을 방지하며, 웨브(W)가 흡입되었다 하더라도 망에 걸려 웨브(W)는 흡입되지 못하고 공기만 흡입되도록 한다.An air permeable body 2b 1 such as a sponge is attached to the inside of the intake chamber 2 around the suction port 2b, and a net 2b 2 is provided on the upper surface thereof, and the air intake is formed around the suction port 2b. The web (W) is prevented from being sucked into the seal (2), even if the web (W) is sucked into the net so that the web (W) is not sucked, so that only air is sucked.

또, 흡인원(2c)의 공기배출구 (2c1)의 개방면적을 조정할 수 있게하여 웨브(W)의 폭방향으로의 길이의 변화에 대응하여 흡인력을 조정할 수 있게 되어 있다.Moreover, the opening area of the air discharge port 2c 1 of the suction source 2c can be adjusted, and the suction force can be adjusted according to the change of the length of the web W in the width direction.

또, 흡기실(2)의 조출방향과 직교하는 방향으로 대향하는 한쌍의 가이드면(2d),(2d)은 조출방향의 하류쪽으로 갈수록 점차 가이드면(2d),(2d)의 사이의 거리가 좁아지는 경사부(2d1),(2d1)를 각각 형성하고, 이들 경사부(2d1),(2d1)의 하류쪽에서의 폭의 길이(W)를 웨브(W)의 폭과 거의 같게하여, 웨브로울(A)에서 인출되는 U자 형상 웨브(W1)의 폭방향의 양쪽 테두리(W2),(W2)가 각각 가이드면(2d),(2d)과 맞닿도록 하여, 웨브(W)의 폭방향으로의 어긋남을 수정하며, 또 가이드면(2d),(2d)을 구성하는 2장의 평판중의 어느 한쪽이나 또는 양쪽 평판 모두를 웨브(W)의 폭방향으로 이동시킬 수 있도록 지지하여 예컨대, 수동핸들등의 조정장치((2d2)를 사용하여, 양 가이드면(2d),(2d) 또는 한쪽 가이드면을 이용시켜서 웨브(W)의 폭길이 변화에 대응하게 한다.In addition, the pair of guide surfaces 2d and 2d facing each other in the direction orthogonal to the feeding direction of the intake chamber 2 gradually increases the distance between the guide surfaces 2d and 2d toward the downstream side of the feeding direction. forming an inclined portion (2d 1), (2d 1 ) is narrowed, respectively, substantially equal to the width of these angled portion (2d 1), the length (W) of the width of the downstream side of (2d 1) the web (W) and, the web roll (a) is so as to respectively abut a guide surface (2d), (2d) each side edge in the width direction of the U-shaped web (W 1) that is drawn out (W 2), (W 2 ) from, the web The deviation in the width direction of (W) is corrected, and either or both of the flat plates constituting the guide surfaces 2d and 2d can be moved in the width direction of the web W. It is supported so that, for example, using an adjusting device (2d 2 ) such as a manual handle, both guide surfaces 2d, 2d or one guide surface are used to cope with a change in the width of the web W.

그리고, 전기한 개방부(2a)로부터 흡인구(2b)까지의 측면에는, 흡기실(2)내로 들어온 U자 형상 웨브(W1)의 처짐량을 검출하여, 전기한 예비조출기구(1)의 작동을 제어하는 검출기(3)를 설치한다.The amount of deflection of the U-shaped web W 1 introduced into the intake chamber 2 is detected on the side surface from the opening portion 2a to the suction port 2b. A detector 3 is installed to control the operation.

이 검출기(3)는 본 실시예의 경우, 조출방향의 아래쪽에 있는 가이드면(2e)의 아래와 위에서, 적당한 간격으로 가이드면의 속에 설치되어 U자 형상의 웨브(W1)를 향하고 있으며, 아래쪽에 설치된 검출기(3a)는 U자 형상인 웨브(W1)의 하단위치가 전기한 조출기구(E)의 간헐작동에 따라, 설정위치 보다도 위쪽으로 이동하여 웨브(W1)의 하단위치가 검출되지 않을때에 예비조출기구(1)를 작동시키며, 설정위치 보다도 아래쪽에 있는 것을 검출한 때에는 예비조출기구(1)의 작동을 정지시키는 역할을 하고, 위쪽에 설치된 검출기(3b)는 웨브가 검출되지 않을때에 조출기구(E)의 작동을 정지시키는 비정상작동 검출용이다. 도면에서 부호(4)는 레지마아크 검출용 센서이고, (F)(F)는 횡접합기이다.In the present embodiment, this detector 3 is installed in the guide surface at appropriate intervals and faces the U-shaped web W 1 below and above the guide surface 2e below the feeding direction. According to the intermittent operation of the feeding mechanism E in which the lower position of the U-shaped web W 1 is provided, the installed detector 3a moves upwards than the set position so that the lower position of the web W 1 is not detected. When not in operation, the preliminary feeding mechanism 1 is operated, and when detecting that the preliminary feeding mechanism 1 is lower than the set position, it stops the operation of the preliminary feeding mechanism 1, and the detector 3b provided above does not detect the web. It is for detecting abnormal operation to stop the operation of the feeding mechanism (E) when it is not. In the drawing, reference numeral 4 denotes a sensor for resist arc detection, and (F) and (F) denote horizontal joints.

이렇게 구성된 웨브공급장치는, 흡인구(2b)에서 흡기실(2)내의 공기가 흡입되고, 이에 따라 발생되는 부압에 의해 웨브(W)가 흡기실(2)의 안쪽으로 U자 형상으로 흡인되어서, 웨브(W)에 일정한 장력을 부여한다.In the web supply device configured as described above, the air in the intake chamber 2 is sucked through the suction port 2b, and the web W is sucked into the U-shape into the intake chamber 2 by the negative pressure generated accordingly. , Give a constant tension to the web (W).

이 상태에서, 조출기구(E)의 간헐적인 작동에 의해 웨브(W)가 조출방향으로 일정한 길이만큼 인출되고, 이것에 의해 흡기실(2)내에 들어간 U자 형상 웨브(W1)의 하단위치가 윗쪽으로 이동하여 처짐량이 적어지면, 이것을 아래쪽에 있는 검출기(3a)가 검출하여 예비조출기구(1)를 작동시키며, 웨브로울(A)에서 인출된 웨브(W1)는 흡기실(2)내로 조출되어서, 그 U자 형상인 웨브(W1)의 처짐량이 증가하면서 웨브(W1)으 하단위치가 서서히 아래로 이동하게 된다.In this state, by the intermittent operation of the feeding mechanism E, the web W is drawn out by a predetermined length in the feeding direction, whereby the lower end position of the U-shaped web W 1 entered into the intake chamber 2. Is moved upward and the deflection amount decreases, the detector 3a at the lower side detects this and activates the preliminary feeding mechanism 1, and the web W 1 withdrawn from the web blower A is taken up in the intake chamber 2. The lower end position of the web W 1 gradually moves downward while being fed to the inside, and the deflection amount of the U-shaped web W 1 increases.

그리고, U자 형상인 웨브(W1)의 하단위치가 아래쪽에 검출기(3a)가 설치된 곳까지 내려오고, 검출기(3a)에서 이것을 검출하면, 예비조출기구(1)의 작동을 정지시켜서, U자 형상인 웨브(W1)의 처짐량은 일정하게 유지된다.Then, when the lower end position of the U-shaped web W 1 descends to the place where the detector 3a is installed at the lower side, and the detector 3a detects this, the operation of the preliminary feeding mechanism 1 is stopped, and the U The amount of deflection of the web W 1 having a shape of a magnet is kept constant.

그후, 조출기구(E)가 간헐적으로 작동될 때마다 전술한 작동이 반복된다.Thereafter, the above-described operation is repeated whenever the feeding mechanism E is operated intermittently.

또한, 전술한 흡기실(2)의 구조는 도면에 표시된 것으로 한정되지 않고 예컨대, 조출방향으로 서로 마주보는 양쪽 원호형상 테두리(2a1)(2a1)의 높이를 같게 형성하였으나, 조출방향 상류쪽에 있는 원호형상 테두리(2a1)를 하류쪽에서 있는 원호형상 테두리(2a1)보다 낮게 형성하여, 예비조출기구(1)에서 공급되는 웨브(W)의 흡기실(2)내로의 인입을 쉽게하며, 하류쪽의 측면(2e)과 U자 형상인 웨브(W1)와의 접촉면적을 확대하여 마찰을 증대시켜서, U자 형상의 웨브(W1)가 앞서가는 것을 방지하는 브레이크로서 이용해도 좋다.In addition, the structure of the above-described intake chamber (2) is not limited to that shown in the drawings, for example, but formed same as the height of each side arc-shaped edge (2a 1) (2a 1) which oppose each other in the feeding direction, the side of the feeding direction upstream to form an arc-shaped rim (2a 1) below the arcuate borders (2a 1) in the side stream in, and easily drawn into the intake chamber (2) of the web (W) supplied in the pre-delivery mechanism (1), The contact area between the downstream side 2e and the U-shaped web W 1 may be enlarged to increase friction, and may be used as a brake for preventing the U-shaped web W 1 from leading.

본 발명은 전기한 구성으로 되어 있어 다음과 같은 장점이 있다.The present invention is of the above configuration has the following advantages.

① 흡인기구를 작동시키므로써, 웨브를 흡인하여 U자 형상으로 처지게 하여 웨브에 일정한 장력을 부여하고, 웨브의 간헐적조출에 따라 U자 형상인 웨브가 서로 마주보는 가이드면을 따라 그 폭방향으로의 위치를 결정하면서 인출되며, 그 U자 형상인 웨브의 처짐량의 변화에 따라 예비조출기구의 작동이 제어되며 U자 형상인 웨브의 처짐량을 일정하게 유지하므로, 관성체를 개재하지 않고, 또, 극단적으로 구부리는 부분을 적게하면서 웨브를 걸수 있고 웨브의 폭방향으로의 이동을 불가능하게 하면서, 이러한 장력을 작용시킬 수 있다. 따라서, 텐션레버나 다수의 종동롤러등의 관성체를 개재하여 극단적으로 구부리는 부분이 많은 상태에서 웨브를 걸어 장력을 부여하는 종래의 방법과 비교하여, 특히, 웨브가 고속으로 간헐조출되어도 웨브에 장력이 전혀 작용되지 않는 웨브의 지연발생을 완전히 방지할 수 있고, 그러므로, 웨브가 폭방향에서 위치를 이탈하지 않으며, 또, 웨브의 모양을 맞추는 경우에도 위치결정의 정확도가 향상되고, 웨브의 재질에 씨실의 올이 있어서 딱딱한 경우라도 웨브 전체에 균일한 장력을 작용시킬 수 있으며, 웨브를 거는 작업도 간단하다.① By actuating the suction mechanism, the web is sucked and deflected into a U shape to impart a constant tension to the web, and the U-shaped webs are guided in the width direction along the guide surfaces facing each other according to the intermittent feeding of the web. It is drawn out while determining the position of the U-shaped web, and the operation of the preliminary feeding mechanism is controlled in accordance with the change of the deflection amount of the U-shaped web, and the deflection amount of the U-shaped web is kept constant. This tension can be exerted while allowing the web to be hooked with extremely low bending and making the web impossible to move in the width direction. Therefore, in comparison with the conventional method of applying tension by hanging the web in a state where there are many bends through an inertial body such as a tension lever or a plurality of driven rollers, in particular, even if the web is intermittently extracted at high speed, It is possible to completely prevent the occurrence of delay of the web in which tension is not applied at all. Therefore, the web does not deviate from the position in the width direction, and the positioning accuracy is improved even when the web is shaped. The weft yarns allow the uniform tension to be applied to the entire web even in a hard case, and the web hanging operation is simple.

② 웨브가 느슨해지는 것을 방지하기 위하여 장력을 크게하면 이것에 대응하여 간헐적으로 작용되는 조출력도 크게 해야 하지만, 본 발명의 웨브공급장치는 웨브가 느슨해지는 것을 완전히 방지할 수 있으므로, 웨브에 작용되는 장력을 최소로 설정할 수있으며, 따라서 조출력도 적게할 수 있어서, 그 조출구동원을 소형화할 수 있다.(2) If the tension is increased to prevent the web from loosening, the coarse output acting intermittently should also be increased in response to this. However, since the web supply device of the present invention can prevent the web from loosening completely, The tension can be set to a minimum, and therefore the output power can be reduced, thereby minimizing the output driving source.

③ 웨브를 흡인하므로, 웨브의 표면에 부착된 먼지나 오물등을 제거할 수 있어, 웨브가 조출하기 쉽게 된다.③ By sucking the web, dust and dirt attached to the surface of the web can be removed, and the web is easy to feed.
