DEFINITION
Classification: 140/92.7
(under subclass 92.3) Devices with features other than and in addition to means for providing a helix and applying it by axial rotation to successive loops, means for positioning said loops, and interrelating control means.
(1) Note. In this subclass, for example, are combinations with means to shape the selvage edges of the assembled fabric, combinations with means to deform the helix after intercoiling, and combinations with automatic control means.
(2) Note. Helix providing includes means for forming a helix with or without subsequent cut-off or means for supplying prepared or preformed helices with or without subsequent cutting means. Coiling, per se, with or without subsequent cut-off is classified in Class 72, Metal Deforming, subclasses 135+; the additional step of guiding and/or positioning or interlacing placing the combination within the scope of subclasses 92.3+. See Class 83, Cutting, for cutting, per se.
(3) Note. Helix applying includes helix guide means as well as means to shift the helix along, and rotate it about the cylindrical axis of said helix. Both shift and rotation may be an inherent function of a helix forming means. The axial shift may be effected solely by engagement of a positively rotated helix with aligned loops.
(4) Note. Positioning includes clamping, guiding, and/or supporting means for successive loops and/or assembled fabric of which said loops form a working edge and means for reeling
assembled fabric and/or feeding said fabric from an assembly or working zone. In addition to the shifting means set forth in (2) Note, above, positioning includes means for relatively shifting a loop row and/or assembled fabric with respect to helix applying means.
(5) Note. Interrelating control includes cyclic interlock means; that is, means for periodic or sequential operations in which the same series of operations on the material are repeated unchanged, in the absence of adjustments of the machine under a particular stimulus such as the presence or absence of material or the application of power to the drive shaft. Interrelating control does not include automatic control, as to which see (6) Note, below. (6) Note. Automatic control includes means to sense a condition or change of condition which means effects a control operation on the apparatus. In this subclass the condition or change of condition is usually a misalignment, tangling, and/or breaking of a projected helix.
