Embodiment Construction

[0030] The following describes an embodiment of the device 2 for removing front and rear trimming from a series of rolls of wound web produced by cutting round materials or rolls. The axial length of the round materials or rolls is approximately equal to the end. The length of the consumed small rolls, such as toilet paper rolls, kitchen towel rolls, etc., is a non-integer multiple of the length. Due to the presence of front and rear trimming, the length of the round material is approximately equal to a non-integer multiple of the length of the finished reel. The total length of the front and rear trimming is usually less than the length of a reel.

[0031] As mentioned in the introduction part of the specification, it must be understood that the concept based on the present invention can also be used in machines or devices for processing other types of articles, as long as the cut edges or residues in the determined and repeated positions of the continuous series of products need...

Abstract

The device comprises: a product advancement path (R); a first conveyor (1) for advancing the products (R) and said trims (RC, RT); downstream of the first conveyor (1), a second conveyor (7) for receiving the products (R); a discharge zone (9) for the trims (RT, RC) between the first conveyor (1) and the second conveyor (7); at least one continuous flexible member (17A, 17B) with gripping elements that can be activated to transfer the products (R) from the first conveyor (1) to the second conveyor (7). The gripping elements comprise deformable sheets (21 A, 21 B) carried by said at least one continuous flexible member (17A, 17B), arranged to grip said products (R) and transfer them from the first conveyor (1) to the second conveyor (7). At least between the first conveyor (1) and the second conveyor (7) and lateral to said advancement path, contrasting surfaces (41 A, 41B) are provided, which cause the deformation of said deformable sheets (21 A, 21B) against the products (R) so as to grip the products with the deformable sheets (21A, 21B) between the first conveyor (1) and the second conveyor (7). Furthermore, at least one portion (18) of the longitudinal length of the continuous flexible member (17A, 17B) is devoid of said deformable sheets (21 A, 21B).

Description

Technical field [0001] The present invention relates to an improvement in a device and method for removing cut edges or residues produced by cutting a longer semi-finished article to subdivide the article into multiple products. In particular, but not exclusively, the present invention relates to a device and method for eliminating cut edges generated by cutting a roll or round material (usually paper, especially thin paper) on which a web is wound, in order to achieve the purpose A reel with a smaller axial length for final consumption. Background technique [0002] The paper processing industry produces large diameter paper reels from continuous production machines. These reels are unrolled and re-wound to form a plurality of round materials or rolls, the diameter of the round materials or rolls is equal to the diameter of the final product, and the axial length is equivalent to the axial length of the source reel. The round material thus obtained must be cut into rolls with ...
