Abstract
Abstract A tape wrapping arrangement requiring but a single drive means, in which tape is shingle wrapped about a rotating mandrel. Preimpregnated tape from its roll has its free end attached to a forward inclined surface of a sleeve carried by the mandrel and is fed in successive layers by a cylindrical roller. The roller is biased toward the mandrel by a double acting air cylinder of a free wheeling carriage. An adjustable knuckle structure interconnects the cylinder piston rod and the roller journal so that selected shingles angles may be wrapped.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
In a tape wrapping arrangement having a rotatable conical mandrel and means for rotating said mandrel about its longitudinal axis, a roll of tape, pressure roller means for shingle wrapping said tape about at least a portion of the lateral surface of said mandrel when said mandrel is rotated, said tape being deposited so that its exposed surface is inclined at an obtuse angle to the mandrel lateral surface, a carriage, means mounting said carriage for free wheeling movement in a direction substantially parallel to said mandrel longitudinal axis with said carriage positionable in response to tape build-up along said mandrel lateral surface, said carriage having a piston therein translatable in a direction normal to the motion of said carriage, and constant pressure control means operatively associated with said piston, a piston rod connecting said piston with said pressure roller means and translatable in response to change in diameter of said mandrel as said pressure roller means is advanced along said mandrel lateral sUrface, said tape wrapping arrangement being so constructed and arranged that a single drive mechanism for rotating said mandrel to shingle wrap said tape operates independent of said carriage and said carriage is moved along an axis parallel to said mandrel longitudinal axis in response to tape build-up.
Claim 2
Dependent Claim
211 words
In a tape wrapping arrangement having a rotatable conical mandrel and means for rotating said mandrel about its longitudinal axis, a roll of tape, pressure roller means for shingle wrapping said tape about at least a portion of the lateral surface of said mandrel when said mandrel is rotated, said tape being deposited so that its exposed surface is inclined at an obtuse angle to the mandrel lateral surface, a carriage, means mounting said carriage for free wheeling movement in a direction substantially parallel to said mandrel longitudinal axis with said carriage positionable in response to tape build-up along said mandrel lateral surface, said carriage having a piston therein translatable in a direction normal to the motion of said carriage, and constant pressure control means operatively associated with said piston, a piston rod connecting said piston with said pressure roller means and translatable in response to change in diameter of said mandrel as said pressure roller means is advanced along said mandrel lateral sUrface, said tape wrapping arrangement being so constructed and arranged that a single drive mechanism for rotating said mandrel to shingle wrap said tape operates independent of said carriage and said carriage is moved along an axis parallel to said mandrel longitudinal axis in response to tape build-up.
Claim 3
Dependent Claim
34 words
The structure in accordance with claim 1 wherein a sleeve carried by said mandrel has an inclined forward surface upon which is secured a free end portion of the first turn of said tape.
Claim 4
Dependent Claim
34 words
The structure of claim 2 wherein said pressure roller means includes a cylindrical roller biased against said mandrel lateral surface, the longitudinal axis of said roller being substantially parallel to said sleeve forward surface.
Claim 5
Dependent Claim
47 words
The structure of claim 1 wherein said carriage includes an elongated fluid cylinder, the mounting means includes on said carriage wheel means journalled said constant pressure, and control means includes a fluid system connected to said fluid cylinder at points above and below the piston travel path.
Claim 6
Dependent Claim
32 words
The structure of claim 1 in which said mandrel rotating mechanism includes a variable speed drive member, and gear transmission means interconnecting said drive member with an axial shaft of said mandrel.
Claim 7
Dependent Claim
68 words
The structure of claim 1 wherein said piston rod is connected to said roller means by an adjustable knuckle arrangement, said knuckle arrangement including a frame having a knuckle member adjustably secured thereto, said piston rod threadedly secured to said knuckle member, and said frame having a pair of substantially parallel arms extending substantially transversely of said frame and containing means for journally supporting said pressure roller means.
Claim 8
Dependent Claim
51 words
The structure of claim 6 wherein said journal support means includes a pair of opposed externally threaded tubular supports in abutment with opposed ends of a cartridge heater and its surrounding sleeve, and journal bearings carried by said roller means and having a corresponding inner race in abutment with said sleeve.
