Abstract
Abstract A lap creel comprising rod shaped carrier elements is used, for example, in the textile industry for winding up textile threads or yarns. For this purpose the rod shaped carrier elements are held together by holding or fixing elements which together with the carrier elements form a circular cage from which the carrier elements protrude radially beyond the holding elements. A plurality of holding elements may be arranged along the lap creel. The individual rod shaped carrier elements have a tapering shape so that the lap creel itself has a conical shape with a largest diameter end and a smallest diameter end. At the largest diameter end the holding element encircles the carrier elements so that the latter face radially inwardly. At the smallest diameter end, the carrier element surrounds the holding element so that the carrier elements face radially outwardly in the form of ribs.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
238 words
A lap creel comprising rod shaped carrier elements (1) each having a cross-section with a long axis of given length and a short axis of a length less than said given length of said long axis, and holding means (2, 3, 4, 5) for said carrier elements (2) to form with said carrier elements a cage having a longitudinal, central axis from which said long cross-section axes extend radially, said carrier elements (1) having a substantially right-angled triangular shape and radially outwardly facing longitudinal edges forming the hypotenuse of the respective triangle whereby these edges extend at an acute angle relative to said central axis of said cage whereby the latter has a conical outer configuration and a cylindrical inner configuration, said lap creel having one end of largest diameter and an opposite end of smallest diameter, said holding means comprising at least one first holding element (5) at said largest diameter end and at least one second holding element (2) at said smallest diameter end, said first and second holding elements (5, 2) being so positioned that said carrier elements extend radially inwardly at said largest diameter end in the area of the respective first holding element (5) and radially outwardly at said smallest diameter end in the area of the respective second holding element, whereby said lap creel is insertable coaxially into another lap creel of the same construction to a definite proportion of its height.
Claim 2
Dependent Claim
238 words
A lap creel comprising rod shaped carrier elements (1) each having a cross-section with a long axis of given length and a short axis of a length less than said given length of said long axis, and holding means (2, 3, 4, 5) for said carrier elements (2) to form with said carrier elements a cage having a longitudinal, central axis from which said long cross-section axes extend radially, said carrier elements (1) having a substantially right-angled triangular shape and radially outwardly facing longitudinal edges forming the hypotenuse of the respective triangle whereby these edges extend at an acute angle relative to said central axis of said cage whereby the latter has a conical outer configuration and a cylindrical inner configuration, said lap creel having one end of largest diameter and an opposite end of smallest diameter, said holding means comprising at least one first holding element (5) at said largest diameter end and at least one second holding element (2) at said smallest diameter end, said first and second holding elements (5, 2) being so positioned that said carrier elements extend radially inwardly at said largest diameter end in the area of the respective first holding element (5) and radially outwardly at said smallest diameter end in the area of the respective second holding element, whereby said lap creel is insertable coaxially into another lap creel of the same construction to a definite proportion of its height.
Claim 3
Dependent Claim
67 words
The lap creel of claim 1, wherein said first holding element (5) in the area of said largest diameter end forms the jacket of a frustum, said frustum jacket having a roughened outer surface (10), said lap creel further comprising a ring groove in said outer surface of said frustum whereby a thread reserve may be freely accessible when it is located on said outer surface (10).
Claim 4
Dependent Claim
71 words
The apparatus of claim 1, wherein said holding means comprise further holding elements in addition to said first and second holding elements, one such further holding element being located at about one third of the length of said carrier elements away from said smallest diameter end, said one further holding element having a larger outer diameter than any other holding element arranged along said one third length of said carrier elements.
Claim 5
Dependent Claim
89 words
The lap creel of claim 2, wherein said substantially right-angled triangular shapes of said carrier elements have step like cut-outs on their radially inwardly directed sides adjacent said largest diameter end and at least partially within said frustum jacket, whereby a free space is formed within the lap creel adjacent said largest diameter end, said free space having an inner diameter larger than the outer diameter of any holding element in the one third length of said lap creel adjacent to said smallest diameter end of the lap creel.
Claim 6
Dependent Claim
30 words
The lap creel of claim 1, wherein said rod shaped carrier elements have a conical cross-section which diminishes in a radially outward direction, said carrier elements further having rounded edges.
Claim 7
Dependent Claim
49 words
The lap creel of claim 1, wherein said hypotenuse forming longitudinal edges of said carrier elements are bow shaped in the area adjacent said smallest diameter end to thereby extend toward said central, longitudinal axis of said cage, whereby said triangular shape is truncated at said smallest diameter end.
