Abstract
Abstract A machine for convolutely winding container bodies having cross sections other than cylindrical comprising a winding mandrel for receiving a lamina and winding the same thereon, together with structure for advancing the wound lamina lengthwise along the mandrel to a position for applying pressure to the wound lamina while disposed on the mandrel and consisting of a frame rotating on an axis corresponding to the axis of rotation of the mandrel. Structure is provided for rotating the frame in the same direction as the winding mandrel but at a lower speed, so that ''''fly-off'''' of the pressure applying means is prevented.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
In a machine for convolutely winding a container body other than one of purely cylindrical cross section from laminar plies; a. a winding mandrel for receiving an end of a lamina and convolutely winding said lamina thereon; b. means for advancing said wound lamina along said mandrel to a position for application of pressure against said wound lamina and for applying a second lamina to said wound lamina; c. means for applying pressure to said wound lamina while the same is disposed on said mandrel throughout rotation thereof comprising; i a frame rotating along an axis coincident with the axis of rotation of said winding mandrel; ii means for rotating said frame in the same direction as said winding mandrel but at a speed lower than the speed of said winding mandrel; iii pressure applying mechanism mounted on said frame including members in contact with said second lamina throughout complete rotation of said container body and the lamina thereof.
Claim 2
Dependent Claim
159 words
In a machine for convolutely winding a container body other than one of purely cylindrical cross section from laminar plies; a. a winding mandrel for receiving an end of a lamina and convolutely winding said lamina thereon; b. means for advancing said wound lamina along said mandrel to a position for application of pressure against said wound lamina and for applying a second lamina to said wound lamina; c. means for applying pressure to said wound lamina while the same is disposed on said mandrel throughout rotation thereof comprising; i a frame rotating along an axis coincident with the axis of rotation of said winding mandrel; ii means for rotating said frame in the same direction as said winding mandrel but at a speed lower than the speed of said winding mandrel; iii pressure applying mechanism mounted on said frame including members in contact with said second lamina throughout complete rotation of said container body and the lamina thereof.
Claim 3
Dependent Claim
30 words
In a machine according to claim 1 wherein means are included for applying a further lamina to said wound lamina at the conclusion of applying pressure to said wound lamina.
Claim 4
Dependent Claim
24 words
In a machine according to claim 2 wherein said further lamina are arranged as a stack thereof movable between lamina applying and retracted positions.
Claim 5
Dependent Claim
30 words
The invention according to claim 3 wherein said pressure applying mechanism is moved out of contact with said wound lamina during application of a further lamina to said wound lamina.
Claim 6
Dependent Claim
148 words
In a machine for convolutely winding a container body other than one of purely cylindrical cross section from laminar plies: a. a winding mandrel for receiving an end of a lamina and convolutely winding said lamina thereon; b. means for advancing said wound lamina along said mandrel to a position for application of pressure against said wound lamina; c. means for applying pressure to said wound lamina while the same is disposed on said mandrel throughout rotation thereof comprising; i. a frame rotating along an axis coincident with the axis of rotation of said winding mandrel; ii. means for rotating said frame in the same direction as said winding mandrel but at a speed lowEr than the speed of said winding mandrel; iii. pressure applying mechanism mounted on said frame including members in contact with said lamina throughout complete rotation of said container body and the lamina thereof.
Claim 7
Dependent Claim

In a machine for convolutely winding a container body other than one of purely cylindrical cross section from laminar plies: a. a winding mandrel for receiving an end of a lamina and convolutely winding said lamina thereon; b. means for advancing said wound lamina along said mandrel to a position for application of pressure against said wound lamina; c. means for applying pressure to said wound lamina while the same is disposed on said mandrel throughout rotation thereof comprising; i. a frame rotating along an axis coincident with the axis of rotation of said winding mandrel; ii. means for rotating said frame in the same direction as said winding mandrel but at a speed lowEr than the speed of said winding mandrel; iii. pressure applying mechanism mounted on said frame including members in contact with said lamina throughout complete rotation of said container body and the lamina thereof.
Claim 8
Dependent Claim
30 words
In a machine according to claim 5 wherein means are included for applying a second lamina to said wound lamina at the conclusion of applying pressure to said wound lamina.
Claim 9
Dependent Claim
24 words
In a machine according to claim 6 wherein said second lamina are arranged as a stack thereof movable between lamina applying and retracted positions.
Claim 10
Dependent Claim
30 words
The invention according to claim 7 wherein said pressure applying mechanism is moved out of contact with said wound lamina during application of said second lamina to said wound lamina.
