Abstract
In order to connect at least two layers of paper or the like, the layers are cut into strips in the connection area and forced out of the plane of the layers alternately and in pairs. To this effect punching and pressing tools with punching teeth may be provided.
Claims21
In an apparatus for producing a packing made of at least two layers of packing paper, in particular craft paper, recycling paper and thin board, which layers cover an object to be packed and are put together along a connecting seam (26) in an adhesive-free manner by a punching and pressing action, the improvement comprising:
- at least a pair of a first and a second punching and pressing tool (19, 20;
- 19', 20';
- 56, 57), which first and second punching and pressing tools (19, 19', 20, 20', 56, 57) are complementary associated with each other;
- punching teeth (21) alternately provided at said first and second punching and pressing tools (19, 20;
- 19', 20';
- 56, 57), which punching teeth (21) of each first and second punching and pressing tool (19, 19', 20, 20', 56, 57) are lined up in a common tool plane (W);
- an interspace (22) between each of said punching teeth (21) with in each case one punching tooth (21) of the first punching and pressing tool (19 and 20, 19' and 20', 56 and 57), being provided to engage with an interspace (22) between two neighbouring punching teeth (21, 38) of the second punching and pressing tool (20 and 19, 20' and 19', 57 and 56), with a width (a) of each interspace (22) essentially corresponding to a width (b) of a corresponding punching tooth (21);
- an edge limiting each punching tooth (21;
- 38) towards a neighbouring interspace (22) being provided as a cutting edge (23);
- a first and a second tool carrier (14, 15;
- 54, 55), wherein the first punching and pressing tool (19, 19', 56) is arranged on the first tool carrier (15, 55) and wherein the second punching and pressing tool (20, 20', 57) is arranged on the second tool carrier (14, 54), and wherein at least one of the tool carriers (14, 15, 54, 55) is movable in a direction perpendicular to said tool plane (W).

- at least a pair of a first and a second punching and pressing tool (19, 20;
- 19', 20';
- 56, 57), which first and second punching and pressing tools (19, 19', 20, 20', 56, 57) are complementarily associated with each other;
- punching teeth (21) alternately provided at said first and second punching and pressing tools (19, 20;
- 19', 20';
- 56, 57), which punching teeth (21) of each first and second punching and pressing tool (19, 19', 20, 20', 56, 57) are lined up in a common tool plane (W);
- an interspace (22) between each of said punching teeth (21) with in each case one punching tooth (21) of the first punching and pressing tool (19 and 20, 19' and 20', 56 and 57, ) being provided to engage with an interspace (22) between two neighbouring punching teeth (21, 38) of the second punching and pressing tool (20 and 19, 20' and 19', 57 and 56, ), with a width (a) of each interspace (22) essentially corresponding to a width (b) of a corresponding punching tooth (21);
- an edge limiting each punching tooth (21;
- 38) towards a neighbouring interspace (22) being provided as a cutting edge (23);
- a first and a second tool carrier (14, 15;
- 54, 55), wherein the first punching and pressing tool (19, 19', 56) is arranged on the first tool carrier (15, 55) and wherein the second punching and pressing tool (20, 20', 57) is arranged on the second tool carrier (14, 54), and wherein at least one of the tool carriers (14, 15, 54, 55) is movable in a direction perpendicular to said tool plane (W);
- deflectors (40) for each of said first and second punching and pressing tools (19, 20;
- 19', 20';
- 56, 57), each of which is supported to be displaceable against a force of a compression spring (47), which is directed against the direction of engagement (E) of the punching tooth (21) of the first punching and pressing tool (19, 19', 56) with the interspace (22) of the second punching and pressing tool (20, 20', 57) and vice versa;
- and
- deflection webs (44) provided at each of said deflectors (40), each of said webs (44) engaging with the interspace (22) between two adjacent punching teeth (21).
