An apparatus for curing cylindrical shaped elements having a liner, especially a liner of a rocket motor sleeve, where the cylindrical shaped elements are cured during rotation in a horizontal orientation. Horizontal rotation produces a liner with a substantially uniform thickness. The apparatus is mobile, compact, and has built-in robust safety mechanisms not compromised by the heat used to effect a cure. The cylindrical rollers are easily cleaned with minimal cross-contamination of one lot to another. Dripping of elastomeric materials from one assembly of rollers onto a stackable assembly of rollers below is eliminated. Each stackable assembly of rollers is independently controlled where each assembly is driven by its own motor, so rotation of one assemble does not affect another assembly of rollers. |

1. An apparatus for rotating and curing cylindrical shaped elements, comprising:
a stackable drawer, comprising:
a frame defining and supporting the drawer, said frame includes a lateral left angle element, a lateral right angle element, a face plate to which is externally attached a guard support holding a gear motor and an electrical connection, a left handle mount, right handle mount, a handle, a drawer cross bar that provides rear support,a left rearward extension of the left angle element, said left extension provides support for a lateral left wheel to facilitate easy of movement of the drawer through a track, and a left V-grooved roller/pulley proximate to an end of the left extension,a right rearward extension of the right angle element, said right extension provides support for a lateral right wheel to facilitate easy of movement of the drawer through a track, and a right V-grooved roller/pulley proximate to an end of the right extension, anda substantially planar assembly of driven cylindrical rollers sequentially driven by a driven sprocket on a gear motor connected to the assembly, where substantially each cylindrical roller includes a first sprocket on one end and a second sprocket on an opposing end, wherein the first sprocket on the first cylindrical roller is connected with a first chain to the driven sprocket on the gear motor, and the second sprocket on the first cylindrical roller is successively connected through a second chain to a second sprocket on a next roller, such that the next roller is driven by the first cylindrical roller, and subsequently therein making the next cylindrical roller a second driven cylindrical roller, which has a first sprocket that successively drives a following cylindrical roller, wherein the pattern repeats until all cylindrical rollers are driven and all rotate in the same direction; a catch tray for collecting and containing any material falling off or through the assembly of cylindrical rollers; a vertical rack comprising a framework of vertical and horizontal elements comprising: a left rear angle and a left rear support element, a right rear angle and a right rear support element, a left front angle and a left front support element, a right front angle and a right front support element, a rack cross bar, a top front angle, and lateral pairs of left and right C-channel forming tracks for each stackable drawer, and
a cover on top of the vertical rack, wherein said vertical rack can hold one said drawer in each pair of tracks; a base comprising a rectangular arrangement of beams, a front skirt plate, wherein said vertical rack is seated on the base; a mechanism to facilitate movement comprising a set of casters including stops and non-abrasive treads;
a set of miniature screw jacks for affecting stabilization and leveling, said set of miniature screw jacks located on the front of the apparatus; and an anti-tip safety mechanism comprising a counter weight guided by a weight constraint cable assembly, and
a drawer constraint cable assembly, where the drawer constraint cable is routed along the rear of the vertical frame guided by a plurality of v-grooved rollers around the left and right V-grooved roller/pulleys of each drawer, across the rack cross bar, and over and looped around v-grooved rollers on the counter weight,wherein when a drawer is pulled open the drawer constraint cable assembly raises the counter weight from a start position to a stop position, where the counter weight can no longer rise, and the opened drawer can not be opened any further, and no other drawers can be opened, andwherein when a drawer is closed the drawer constraint cable assembly lowers the counter weight from a stop position to a start position, where the counter weight can rise, and another drawer can be opened. |
