前記目的を達成するために、本発明のウェブの接合方法は、ウェブを巻回した第一ロールとウェブを巻回した第二ロールとを回転可能なターレット機構に巻き戻し可能に配置するステップと、前記第一ロールのウェブを巻き戻すステップと、切断刃を有しウェブの搬送路に対し上側に配置された上刃ドラムと、切断刃を有しウェブの搬送路に対し下側に配置された下刃ドラムによって、前記第一ロールのウェブの後端部と前記第二ロールのウェブの先端部を挟圧しながら同時に切断し接合部を形成するステップと、前記接合部を形成した後、切断後の前記第一ロールのウェブと前記第二ロールのウェブへの前記上刃ドラムと前記下刃ドラムによる挟圧力を弱め、前記第二ロールのウェブに接合されない前記第一ロールのウェブを引き抜くステップと、接合テープを保持しウェブの搬送路に対し上側に配置された接合ドラムと前記下刃ドラムにより、切断された前記第一ロールのウェブ後端と前記第二ロールのウェブ先端と挟圧しながら、前記接合部に接合テープを貼り付けるステップと、を備えることを特徴とする。 In order to achieve the above object, a method of joining webs of the present invention comprises the steps of: unrollably arranging a first roll wound with a web and a second roll wound with a web on a rotatable turret mechanism. The step of rewinding the web of the first roll, an upper blade drum having a cutting blade and disposed above the transport path of the web, and a cutting blade disposed below the transport path of the web Simultaneously cutting the rear end of the web of the first roll and the front end of the web of the second roll with the lower blade drum to form a joint, and forming the joint, and cutting It weakened clamping force by pre-Symbol the upper blade drum and the lower knife drum to the first roll of web and the second roll of web after, withdrawing the second roll are not joined to the web the first roll of web Ste Flop and by the lower knife drum and splicing drum for holding the splicing tape is disposed on the upper side relative to the conveying path of the web, cutting web tip and clamping pressure of the web trailing end of the first roll second roll And attaching a bonding tape to the bonding portion.

前記目的を達成するために、本発明の機能性フィルムの製造方法は、第一ロールのウェブを巻き戻し、前記第一ロールのウェブに塗布液を塗布し、前記塗布液を乾燥するステップと、前記第一ロールのウェブと第二ロールのウェブを上記記載の接合方法により接合するステップと、前記第二ロールのウェブを巻き戻し、前記第二ロールのウェブに塗布液を塗布し、前記塗布液を乾燥するステップと、を少なくとも備えることを特徴とする。 To achieve the above object, the method for producing a functional film of the present invention, the step of unwinding a first roll of web, the coating liquid is applied to the web of the first straight Lumpur, drying the coating liquid If the steps of bonding the first straight Lumpur web and the second b Lumpur web by joining method, wherein the rewind said second roll of web, coating the second b Lumpur web Applying a liquid, and drying the coating liquid.
