Definitions
- the present invention relates to the field of machine feeding or production lines in strips, especially in cardboard strips, more particularly narrow cardboard strips, or other strips made more particularly from a semi-rigid material, and attaching two strips to one another wound on reel mandrels, one of which is a replacement web awaiting unwinding and the other the pull-up web carrying out said feed and relates to a method connecting strips, by double bonding, butt. It also relates to a band connecting device, by double bonding, end to end, suitable for the implementation of said method.
- narrow cardboard strips we mean cardboard strips whose width is in particular between about 25 mm and 500 mm.
- Each upstream or downstream strip has two opposite faces respectively internal and external, whose inner face is the one that is in contact with the mandrel, and terminates at each of its connection ends by a joined edge, whose contiguous edge of the strip downstream results from its transverse cutting.
- It comprises a fixed frame, a single-sided adhesive tape having an adhesive face, two first axis cylinders perpendicular to said planes and a second axis cylinder parallel to said planes fixed on the frame, a movable support surface provided to support, in operation, the connecting end and the adhesive tape stuck on the outer face of the latter extending on either side of its contiguous edge, a cutting head provided to cut transversely along a substantially parallel cutting line or parallel to said reference planes, the downstream band to realize its connecting end, two guide rollers, also called return rollers, fixed on the frame and guiding the downstream band, axes parallel to said planes of reference, stop or blocking means fixed on the frame and provided to stop or boquer the unwinding of the downstream band.
- the device comprises a rectangular-shaped pressing element comprising two opposite inner and outer faces, the outer face of which forms a connecting face enabling it to be connected to the rods of the first two jacks and the inner face forming the support surface.
- the connecting end provided with adhesive tape, applied flat against the support surface, the latter comprises at least one suction opening of a suction cup allowing to retain by suction the outer face of said end applied against the support face.
- the movable support surface is provided to be displaced, by means of the first moving means, along an axis perpendicular to said reference planes, between a waiting position in the waiting plane and a connection position in the connection plane.

- the counter blade is generally arranged between the connection plane and the waiting plane, and is made movable to be displaced, thanks to the second displacement means, along an axis parallel to said planes and perpendicular to the axis of the or each roller guide, between a withdrawal position, remote from the plane of the blade, said cutting plane, to allow the passage of the support surface during its movement to the connection plane and an advanced position in the cutting plane.
- the object of the present invention is to overcome these drawbacks by proposing a method, and a connecting device that is suitable for implementing said method, making it possible to reinforce the resistance of the joint of the connection between them of a replacement strip and of a pull-down strip that terminates and prevent any delamination, tearing or separation effects of their respective connection ends.
