Abstract

A connector arrangement for connecting web ends (5), in particular an endless filter web, comprises two elongate elements which each have at least one elongate leg (1, 2) for fastening on one of the web ends (5), and a longitudinal flank (9) directed away from the web end (5). In a first longitudinal-section plane the longitudinal flank (9) has a first periodic contour, which engages in a corresponding contour of the other element respectively. In a second and third cross-section plane extending parallel to the first longitudinal-section plane, the elements each have second and third periodic contours (10, 11), which engage in a form-fitting manner in respectively corresponding contours (10, 11) of the other element respectively. The first to third contours form a groove (13, 13′) and a tongue (12) in at least one cross-section plane.

Dependent claims

Connector arrangement for connecting the ends of a web, comprising:

two elongate elements, each elongate element having a longitudinal direction parallel to the edge of one of the web ends and a transverse direction perpendicular to the longitudinal direction, at least one elongate leg for fastening on one of the web ends, and a longitudinal flank which is directed away from the web end, wherein for connecting the web ends, the elongate elements are oriented with their flanks in engagement and their elongate legs extending in opposite directions,
wherein each longitudinal flank has a first contour extending in the longitudinal direction of the elongate elements in a first longitudinal-section plane substantially parallel to a plane defined by the longitudinal and transverse directions of the at least one elongate leg, wherein the first contour is configured so that the first contour of one elongate element engages in a corresponding first contour of the other elongate element respectively,
wherein each longitudinal flank has second and third contours in second and third longitudinal-section planes, respectively, extending parallel to the first longitudinal-section plane, wherein the second and third contours are different from the first contour and are configured so that the second and third contours of one elongate element engage in a form-fitting manner in third and second contours, respectively, of the other elongate element, and
wherein the first and third contours together of each longitudinal flank form tongues and the second and third contours together of each longitudinal flank form grooves in at least one cross-section plane extending perpendicular to the longitudinal direction, wherein the tongues and the grooves of each longitudinal flank alternate, and wherein the alternating tongues and grooves of one elongate element engage the alternating grooves and tongues respectively, of the other elongate element to form tongue-and-groove joints.

Connector element for use in a connector arrangement for connecting the ends of a web, the connector element having a longitudinal direction parallel to the edge of one of the web ends and a transverse direction perpendicular to the longitudinal direction, and comprising:

at least one elongate leg for fastening on one of the web ends, and a longitudinal flank which is directed away from the web end,
wherein the longitudinal flank has a first contour extending in the longitudinal direction of the connector element in a first longitudinal-section plane substantially parallel to a plane defined by the longitudinal and transverse directions of the at least one elongate leg, wherein the first contour is configured to engage in a corresponding first contour of another, identical connector element respectively,
wherein the longitudinal flank has second and third contours in second and third longitudinal-section planes, respectively, extending parallel to the first longitudinal-section plane, wherein the second and third contours are different from the first contour and are configured to engage in a form-fitting manner in respective third and second contours of another, identical connector element,
wherein the first and third contours together form tongues and the second and third contours together form grooves in at least one cross-section plane extending perpendicular to the longitudinal direction, wherein the tongues and the grooves alternate, and wherein the alternating tongues and grooves of the connector element are configured to engage with alternating grooves and tongues respectively, of another, identical connector element to form tongue-and-groove joints, and
wherein the leg is provided with channels along an exterior side.
