A threading device for double twist thread twisting frames which have a spindle and a suction device movable toward a storage disc on the frame. A service carriage is movably mounted on the frame along one side thereof. A threading head is movably mounted on the service carriage and is movable between a rest position remote from the spindle and a threading position in which it is in registry with the upper end of the spindle. The threading head has on its side facing the spindle axis an inlet slot that extends parallel to the spindle axis. A thread channel is provided adjacent the bottom of the inlet slot and, in the threading position of the threading head, is in registry with the spindle axis. At least two holder elements are mounted on the frame and are spaced one above the other and substantially in the plane of movements of the inlet slot on the threading head. A piece of thread extends between the two holder elements and presents same to the threading head upon movement thereof toward the threading position.

An apparatus for connecting a first web of a web-shaped material unwinding from a first roll with the beginning of a second web of a web-shaped material unwinding from a second roll. The beginning of the second web is cemented to a transfer element by means of an adhesive area applied thereto. The transfer element is then moved toward the first web and/or the first web is moved toward the transfer element and the transfer element is accelerated to a speed corresponding to the speed of the expiring first web while a loose initial region of the second web is concurrently pulled tighter and the beginning of the second web is then cemented to the first web by means of another adhesive area applied to the beginning of the second web facing the side averse the first adhesive area and is pulled away from the transfer element. The acceleration of the second roll is carried out by the tension exerted by the first web after the beginning of the second web has been cemented to the expiring first web, and tension overloads and sudden loads exerted on the webs and the points of cementation between the web during initial acceleration being prevented by conducting the respective web over a force storage means which yields under increased tension on the path of the web to further processing stations.
