Abstract: An improved tape wheel for shuttleless looms having flexible guide members carried thereon for retaining a flexible tape in close proximity with the outer periphery of the tape wheel and for releasing the same therefrom during the tape's function of inserting and withdrawing a weft carrier from a shed of warp threads.

Abstract: A web forwarding device wherein a web is friction driven by a drive means associated with a web pressure backing roll and a pair of pressure arms. The amount of wrap and tension around the backing roll is controlled by a pair of free floating pivotally mounted and interconnected pressure arms which hold the web on the roll. The pressure arms are adjustably mounted to control the distance between the axis of rotation of the roll and the pivot point.

Abstract: Commercially available cassette cartridges which are reel-to-reel magnetic tape cartridges of a standard size and design can be converted to endless loop cartridges by replacing one of the reels with an auxiliary drive assembly including a drive hub with adjacent guides to insure positive driving in contact between the tape and the drive hub and replacing the other reel with a free wheeling tape platen with an endless loop of magnetic tape wound spirally thereon which is threaded so its innermost convolution is pulled from the hub of the platen by the combined action of the capstan drive and the forward reel drive of the recorder to insure positive tape transport without wow and flutter and returns to the peripheral tape convolution on the platen.
