Abstract
Abstract A maypole-type braider for the reinforcing of hose and other tubular products and for the production of ropes, cables and the like, having mechanism for directing strand supply carrier spindles in intersecting serpentine paths around a braiding point, the mechanism including a circle of carrier spindle drivers, cooperating means on the drivers and carrier spindles for retaining each carrier spindle in contact with a driver while it is being driven thereby and for transferring each carrier spindle from a driver to a next adjacent driver of the circle, said cooperating means eliminating the necessity of a track plate or other stationary part acting upon the carrier spindles, the braider also including means for maintaining a strand pay-off point of each carrier substantially on a line drawn through the center of the spindle and the braiding point during the travel of the carrier spindles in their serpentine paths around the braiding point, the last-mentioned means contributing to the operation of the carrier spindle retaining and transfer means.

107 words
In a braiding machine, a support member, a series of drivers carried by said support member arranged in a circle around a braiding point, means to rotate adjacent of said drivers in opposite directions, a series of strand supply carrier spindles and means to cause said spindles to be driven by said drivers for travel in serpentine intersecting paths in opposite directions around said braiding point, the improvement comprising means for maintaining a point on each of said carrier spindles substantially on a line drawn through the center of the carrier spindle and said braiding point during the travel of said carrier spindles around said braiding point.
Claim 2
Dependent Claim
107 words
In a braiding machine, a support member, a series of drivers carried by said support member arranged in a circle around a braiding point, means to rotate adjacent of said drivers in opposite directions, a series of strand supply carrier spindles and means to cause said spindles to be driven by said drivers for travel in serpentine intersecting paths in opposite directions around said braiding point, the improvement comprising means for maintaining a point on each of said carrier spindles substantially on a line drawn through the center of the carrier spindle and said braiding point during the travel of said carrier spindles around said braiding point.
Claim 3
Dependent Claim
53 words
A braiding machine according to claim 1 wherein said means for maintaining a point on each of said carrier spindles substantially on a line drawn through the center of the carrier spindle and said braiding point comprises means to rotate each carrier spindle on its axis as it is driven by said drivers.
Claim 4
Dependent Claim
59 words
A braiding machine according to claim 2 wherein said means to rotate each carrier spindle on its axis as it is driven by said drivers comprises a planetary gear system associated with each driver and including a gear in intermeshing engagement with a gear associated with a carrier spindle as said carrier spindle is being driven by said driver.
Claim 5
Dependent Claim
109 words
A braiding machine according to claim 3 wherein said drivers comprise rotors, there is means for rotating each rotor of each driver on its axis with the rotors of adjacent drivers rotating in opposite directions, and wherein said planetary gear system includes a gear associated with each driver, said gear having a common center with the rotor of the driver with which it is associated and being fixed against rotation relatively to said rotor, and intermediate gears associated with each driver with each intermediate gear in intermeshing engagement with one of said first-mentioned gears, and wherein said gear associated with each carrier spindle is affixed thereto for rotation therewith.
Claim 6
Dependent Claim
93 words
A braiding machine according to claim 1 wherein said drivers comprise rotors with adjacent rotors of said circle of drivers defining carrier spindle transfer points and being in substantially tangential relationship at said carrier spindle transfer points, carrier spindle-receiving pockets in the rotors, and means for maintaining a carrier spindle in a pocket of each rotor for travel with said rotor between said carrier spindle transfer points and for transferring each carrier spindle from the said pocket of one rotor to a pocket of an adjacent rotor at said carrier spindle transfer points.
Claim 7
Dependent Claim
31 words
A braiding machine according to claim 5 wherein said means for maintaining the carrier spindles within the pockets of the rotors comprises mechanical cooperative means on said carrier spindles and rotors.
Claim 8
Dependent Claim
53 words
A braiding machine according to claim 6 wherein said cooperative means on said carrier spindles and rotors comprise means carried by each carrier spindle and defining tracks, and track followers carried by each rotor with one of said track followers in cooperative engagement with a track of a carrier traveling with said rotor.
Claim 9
Dependent Claim
73 words
A braiding machine according to claim 7 wherein said tracks comprise roller tracks and said track followers comprise rollers, and said roller tracks are of a length and are so positioned in relation to the rotation of the carrier spindle on its axis that the roller in cooperative engagement with a roller track rides off of said roller track when the rotor has carried the carrier spindle to a carrier spindle transfer point.
Claim 10
Dependent Claim
88 words
A braiding machine according to claim 6 wherein said cooperative means on said carrier spindles and rotors comprises means carried by each carrier spindle defining two roller tracks of semicircular configuration with the tracks at different levels and in opposed relationship and there are rollers carried by adjacent rotors with a roller of one of the adjacent rotors being positioned for engagement with the roller track at one level and a roller of the other rotor being positioned for engagement with the roller track at the other level.
Claim 11
Dependent Claim
78 words
A braiding machine according to claim 9 wherein said tracks are of a length and are so positioned in relation to the rotation of the carrier spindles on their axes that a roller of a rotor rides of the roller track of a carrier spindle at its level and the roller of an adjacent rotor rides onto the roller track of said carrier spindle at its level when said carrier spindle passes through a carrier spindle transfer point.
Claim 12
Dependent Claim
92 words
