将两卷纸材料连接的接合装置，包括接合装置的展开装置
摘要：
一种将来自被进给的卷轴(BA)的第一卷纸材料和来自备用卷轴(BB)的第二卷纸材料(NB)连接的接合装置，包括两个头(107A，127A；107B，127B)，每个头包括：与夹杆(143A，145A；143B，145B)相连的滚筒(129A；129B)，以保持第二卷纸材料(NB)的初始边；与滚筒(129A；129B)共同操作的反压件(109A；109B)，以将第一和第二卷纸材料(NA，NB)彼此压靠在一起；切割件(111A；111B)；移动单元(113A；113B)，反压件(109A；109B)和切割件(111A；111B)在其上运送。第一公共控制件(121)通过将运动交替地传递给一个或另一个头的移动单元，从而将第一和第二卷纸材料压紧在滚筒(129A；129B)和反压件(109A；109B)之间；切割第一卷纸材料；和释放第二卷纸材料。
摘要（英）：

A splicing device to join a first web material coming from a reel being fed (BA), to a second web material (NB), coming from a reel standing by (BB), comprising two heads (107A, 127A; 107B, 127B), each of which comprises: a roller (129A; 129B) associated with a clamping bar (143A, 145A; 143B, 145B) to hold an initial edge of the second web material (NB); a counter-pressure member (109A; 109B) cooperating with said roller (129A; 129B) to press said first and second web material (NA, NB) against each other; a cutting member (111A; 111B); a moving unit (113A; 113B), on which said counter-pressure member (109A; 109B) and said cutting member (111A; 111B) are carried. A first common control member (121) is provided to cause, by the movement it imparts to the moving unit of one or other head alternately: pinching of the first and second web material between the roller (129A; 129B) and the counter-pressure member (109A; 109B); cutting of the first web material; and release of the second web material.
