Problems solved by technology

[0013] Similar problems arise in other situations when it is necessary to remove cuts from a series or line of products obtained by cutting semi-finished products of larger size or, more simply, from a series of items or manufactured products advancing along a production line. edges or crumbs

Embodiment Construction

[0045] Specifically referring first to the schematic side views in FIGS. 1 to 4 and the cross-section in FIG. 5, the device generally indicated by 1 is located downstream of the only schematically indicated cutting machine 3, which includes a circular blade T or Other equivalent cutting members, such as band saws, to divide the round material L of considerable length into a series of rolls R of the same length as the final product. The cutting machine 3 also generates a head cut edge Rt and a tail cut edge Rc for each round material that must be removed from the device 1, while the rolls R must be conveyed to the conveyor 7, which then directs them towards the known type And the packaging machine not shown conveys. This type of cutting machine is known and will not be described here.

[0046] The cutting machine 3 may have one or more channels. The example shown shows only two adjacent channels (Figure 5), along which the circular material cut simultaneously by the cutting machine...

Abstract

The device comprises at least one continuous movable flexible member (23) carrying a series of contact members (29, 29A, 29A, 29B). A part of the movable flexible member does not have said contact member to allow the cutting edges (Rc, Rt) to fall. There is also provided a longitudinal support element (21) of at least one product (R, R1, RN) parallel to the movable flexible member, the mutual position of said flexible member and said longitudinal element being such that the product is aligned with the flexible member. The contact members (29, 29A, 29B) are advanced in contact with the longitudinal elements. A pusher (11) inserts a series of products with corresponding cut edges between said flexible member and said longitudinal support element. The flexible member (23) is controlled by variable speed so as to convey its portion without contact member at a time to the position of the trailing and head trimmings (Rc, Rt) of the two sequential series of products.

Description

Technical field [0001] The present invention relates to a device for removing debris or edge trimming in the production of rolls of wound webs such as paper, for example, by cutting longer rolls or "logs" Cut into several parts to produce rolls such as toilet paper and kitchen towels. [0002] More generally, the present invention relates to a device for removing cut edges or debris from series or rows of products. Background technique [0003] The production of rolls of wound webs, such as toilet paper, kitchen towels, etc., is performed by cutting the round material into several parts. The round material has the same diameter as the final roll but is larger than the intended use. The shape has an initial roll of greater length. The round material is then cut into several parts by a cutting machine in order to obtain a roll of the required length. During this operation, in order to discard the part of the edge material that is often damaged and that is irregularly wound, head an...
