Abstract
Abstract A creeling device for bobbins, especially for bobbins with conical sleeves, which includes a clamping member with resilient ribs and with a limited spring stroke of the resilient ribs. Preferably the creeling device comprises a central or hub portion surrounded by an annular resilient portion radially spaced from the hub portion and provided with ribs extending in the axial direction of the annular resilient portion which latter has one end resiliently connected to the hub.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A creeling device for textile bobbins, especially for bobbins with conical sleeves, having an interior of differing tapering angle, consisting of a spindle upon which a clamping member of elastomeric synthetic material positively frictionally engaging the interior is arranged having a central section with an outer circumference as well as an axis and resilient ribs distributed outwardly away from though extending axially of the outer circumference of said central section in radially spaced relationshup thereto, said central section including means for limiting the radially inward movement of said ribs resiliently toward the axis of said central section.
Claim 2
Dependent Claim
97 words
A creeling device for textile bobbins, especially for bobbins with conical sleeves, having an interior of differing tapering angle, consisting of a spindle upon which a clamping member of elastomeric synthetic material positively frictionally engaging the interior is arranged having a central section with an outer circumference as well as an axis and resilient ribs distributed outwardly away from though extending axially of the outer circumference of said central section in radially spaced relationshup thereto, said central section including means for limiting the radially inward movement of said ribs resiliently toward the axis of said central section.
Claim 3
Dependent Claim
42 words
A device according to claim 1, which includes an undivided annular member substantially concentrically surrounding said central section in radially spaced relationship thereto and carrying said ribs, said annular member having only one of its ends resiliently connected to said central section.
Claim 4
Dependent Claim
63 words
A device according to claim 2, in which the means for limiting the radially inward movement of said ribs are formed by a portion of said central section acting as abutment for said ribs and located at that end portion of said annular member which is remote from that one end of said annular member which is resiliently connected to said central section.
Claim 5
Dependent Claim
53 words
A device according to claim 1, in which said ribs are connected at one end only to said central section while leaving a gap that remains between said central section and said ribs in conformity with the intended maximum stroke of said ribs in radial direction toward the axis of said central section.
Claim 6
Dependent Claim
29 words
A device according to claim 4, in which the width of said ribs increases arcuately in the direction away from the connection of said ribs with said central section.
