Circular Comb Comprising a Guide Element

摘要

The invention relates to a circular comb (R) for a comber having a basic body (18, 20), which is fastened on a circular comb shaft (15) in a rotationally locked manner and supports, on the outer circumference thereof, at least one comb clothing (G), the clothing tips of which form an outer enclosing circle (HK), and a guide element (7, 7a) fastened on the circular comb is provided following—as viewed in the combing direction (L) of the comb clothing—the basic body supporting the comb clothing (G), said guide element having at least two mutually adjacent guide surfaces (f1-f3), wherein the first guide surface (f1), which adjoins the basic body (18, 20), is arranged within the enclosing circle (HK) and with substantially consistent radial clearance (e) from the enclosing circle, and the adjoining second guide surface (f2) forms an obtuse angle (α) with the first guide surface (f1). In order to better control the airflows in the region of the join, it is proposed that the radial clearance (e) of the first guide surface (f1) of the guide element (7a) from the enclosing circle (HK) is between 4-10 mm and the second guide surface (f2) forms an angle (α) between 130°-170° with the first guide surface (f1), wherein the rear end (H)—as viewed in the combing direction (L) of the comb clothing (G)—of the second guide surface (f2) has a radial clearance (M) between 8-18 mm from the enclosing circle (HK) of the comb clothing and the length (12) of the second guide surface (f2) is at least twice as great as the length (11) of the first guide surface (f1), as viewed in the circumferential direction of the circular comb (R).

1. A circular comb (R) for a comber having a basic body (18, 20), which is fastened on a circular comb shaft (15) in a rotationally locked manner and supports, on the outer circumference thereof, at least one comb clothing (G), the clothing tips of which form an outer enclosing circle (HK), and a guide element (7, 7a) fastened on the circular comb is provided following—as viewed in the combing direction (L) of the comb clothing—the basic body supporting the comb clothing (G), said guide element having at least two mutually adjacent guide surfaces (f1-f3), wherein the first guide surface (f1), which adjoins the basic body (18, 20), is arranged within the enclosing circle (HK) and with substantially consistent radial clearance (e) from the enclosing circle, and the adjoining second guide surface (f2) forms an obtuse angle (α) with the first guide surface (f1), characterized in that
the radial clearance (e) of the first guide surface (f1) of the guide element (7a) from the enclosing circle (HK) is between 4-10 mm and the second guide surface (f2) forms an angle (α) between 130°-170° with the first guide surface (f1), wherein the rear end (H)—as viewed in the combing direction (L) of the comb clothing (G)—of the second guide surface (f2) has a radial clearance (M) between 8-18 mm from the enclosing circle (HK) of the comb clothing and the length (12) of the second guide surface (f2) is at least twice as great as the length (11) of the first guide surface (f1), as viewed in the circumferential direction of the circular comb (R).
