る。<Conventional technology> Conventionally, as this type of web supply device,
As disclosed in JP-158629, a tension lever is provided to be vertically swingable on the downstream side in the pulling-out direction of the feeding portion,
The web is stretched over a plurality of rotatable tension rollers pivotally supported by the tension lever and a plurality of guide rollers disposed opposite to the tension rollers, and the weight of the tension lever and the tension roller is reduced. A constant tension is applied to the web, and when the tension lever swings due to intermittent withdrawal of the web, this is detected by a detector and the feeding section is operated to feed the web from the web roll and supply the web to the downstream side. In some cases, the tension lever is returned to an initial state, thereby always tensioning the web while reducing the pulling force of the web.

低下するという問題がある。<Problems to be solved by the invention> However, in such a conventional web supply device,
Since the tension lever swings at a speed corresponding to the web withdrawing speed, especially when the web is intermittently withdrawn at a high speed, the inertia works due to the weight of the tension lever and the tension roller when the tension lever swings, and the angle exceeds the required angle. In addition, the following delay occurs with respect to the drawn web, and the web is stretched through a plurality of tension levers and guide rollers that follow the drawn web. When the web is intermittently pulled out, a phenomenon occurs in which the web is pulled out more than necessary due to the rotational inertia of the large number of driven rollers and returns, and as a result, there is a timing at which no tension is applied to the web, and the web tends to sag. , The web may be displaced in the width direction perpendicular to the pull-out direction, or registration marks may be Subjected positioning accuracy in the case of a pattern combined web is positioned on the basis of the registration mark is lowered.

題もある。Furthermore, since the web is often bent extremely by a large number of driven rollers, if the web material is stiff and hard, wrapping around the driven rollers is poor and uniform tension cannot be applied to the entire web. In addition, there is a problem that the work of rolling the web over a number of driven rollers is troublesome.

ことができる。A constant tension is given to the web by sucking the web from the suction port and sucking the web into the suction chamber in a U-shape with the negative pressure, and the width of the web drawn from the web roll by intermittent withdrawal of the web. The U-shaped web is positioned in the width direction by being shifted in the direction, and the detector detects that the insertion depth of the U-shaped web has become shallow, so that the feeding portion is started to operate and the web is fed, and the U-shaped web is fed. Since the insertion depth of the character-shaped web is kept constant, the web can be stretched over the web and the tension can always be uniformly applied so as not to be able to move in the width direction of the web while reducing the extremely bent portion without interposing the inertial body. .

ェブも架け渡し作業も簡単である。Therefore, even if the web is stretched at high speed and intermittently pulled out, the web is completely bent as compared with the conventional one in which the web is stretched over and has a lot of extremely bent portions via an inertial body such as a tension lever and many driven rollers. The timing at which tension is not applied cannot be achieved, and the occurrence of sagging of the web can be completely prevented, so that the web does not shift in the width direction, and the positioning accuracy is improved when patterning the web, and the material of the web Even when hard and stiff, the entire web can be given a uniform tension, and the web can be easily laid.

できて該引出しの駆動源を小型化が図れる。If the tension is increased to prevent the slack of the web, the intermittent withdrawal force must be correspondingly increased. However, the web supply device of the present invention can completely prevent the occurrence of the slack of the web, so The tension can be set to a minimum, and accordingly, the pull-out force can be reduced, and the drive source of the drawer can be reduced in size.
ウェブを吸引するので、ウェブの表面に付着したホ
コリやゴミ等を除去でき、ウェブが引出し易くなる。Since the web is sucked, dust, dust and the like attached to the surface of the web can be removed, and the web can be easily pulled out.
