A device for removal of slips from a continuously transported slip web is composed of an advancement roll pair which continuously advances and holds the slip web. A blade cylinder pushes a respective lead end of a slip into an open gripper of a gripper cylinder. A device is arranged between the advancement roll pair and the blade cylinder and provides transverse perforated lines. A rotating tear-off segment cooperates with the blade cylinder. In order to enable a simple and rapid adaptation to different slip formats, the advancement speed of the advancement rolls, the transverse perforating device and the angle of action of the tear-off segment are correspondingly changed relative to the blade cylinder.

An adhesive application device is provided with suspended and free floating adhesive rollers positioned on a support plate. The rollers form an adhesive chamber with a housing placed against them. The support plate is positioned in the machine frame, laterally from the adhesive rollers, so that it can be swung around a vertical shaft. The support plate is provided with support pieces, upon which the housing is attached in a removable manner, so that good accessibility is provided and so that the adhesive application device can be maintained properly and cleaned quickly in a simple manner.

A device for transferring slips of paper from a first rotationally-driven cylinder to a second rotationally-driven cylinder. Each cylinder has a pincers-like gripper including a controlled, pivotal jaw that has the form of a blade cooperating with a rigid jaw of the same cylinder. The pivotal jaw also operates as a controlled insertion blade that slides the slips of paper into the opened gripper of the other cylinder. The structural design of the device is simplified due to the fact that the pivotal blade-shaped jaw of each cylinder is provided with a second control that can be activated on command which deactivates the control of the pincers movement of the jaw and controls the jaw in such a way that it functions as the insertion blade.

A device for applying adhesives includes an adhesive chamber, the front side of which is closed by an adhesive roller with a vertical rotational axis which, in cooperation with one vertical side wall of the chamber, delimits a return gap for unremoved adhesive. A sealing roller is arranged parallel to the adhesive roller, forms a gap for the adhesive in cooperation with the adhesive application roller and is sealed relative to the other vertical side wall of the chamber by sealing elements. A glue application roller can be adjusted such that it adjoins the adhesive roller, receives preferably formatted glue sections from the adhesive roller and transfers the glue sections to the work pieces on which the glue needs to be applied. In order to prevent accumulations of the adhesive in front of the return gap which are discharged in uncontrolled fashion, a strip of flexible and/or elastic material is fastened to the side wall that delimits the return gap. The free end of the strip adjoins the surface region of the adhesive roller which enters the chamber.

A device for pulling open continuously cross-conveyed tube sections for the purpose of forming bottoms in the manufacture of sacks has support tubes provided in pairs and connected to vacuum sources by lines. Each of the support tubes forms the coupler of two parallel connecting rods housed in a machine frame so as to rotate and is equipped with a row of radial suction units. A crank is connected to a shaft of a parallel connecting rod. A crank pin, supporting a slide ring or a roll, slides in a radial guide attached to a shaft. The shaft of the guide is offset relative to the parallel connecting rod shaft such that an essentially translational movement corresponding to the conveyance speed is superimposed on the opening movement of the row of suction units. In order to achieve a better opening of the tube section ends even at higher conveyance speeds, the radial guide is formed in a curved shape such that the time of uniform motion of the suction units and the tube section is lengthened.

The invention concerns a bag machine for attachment of strip sections or labels to a passing bag base, including an application drum with a gripper which can be actuated to open and close, and with a knife interacting with the gripper. In this bag machine, the knife is arranged on a second drum running parallel to the application drum. The second drum also features a gripper which interacts with a knife arranged on the application drum.
