Abstract:
A thread drawing-in head for a drawing device in which at least two heads, each having a warp thread guide passage, are disposed in series such that the passages can align in series, to clamp a heald therebetween in such a manner that a hole of the heald is aligned with the passages. Each thread drawing-in head comprises a first portion having a groove that defines the passage, the groove extending therethrough longitudinally, the first portion being rotatably supported, a second portion that is supported in such a manner as to be movable toward and away from the first portion to close and open the groove and rotatable together with the first portion, a guide groove that is formed at one end of the head that is comprised of the first and second portions, the guide groove being defined by a bottom surface that extends substantially perpendicularly to the groove to engage with a surface of a heald to be clamped and a slanted surface that extends divergently from each end of the bottom surface, and a projection that is formed at the other end of the head, the projection having a top surface that engages with the surface of a heald to be clamped and a slanted surface that extends from each end of the top surface so that the projection fits into the guide groove of another head.
Abstract:
Here is disclosed an apparatus for successive drawing-in of warp through repsective reed blade gaps of a reed in the automatic loom, comprising a nozzle disposed above the reed which is movable transversely of the reed blades and extended from an upper portion to a bottom side thereof by a warp end feeding slit having its upper opening serving as a warp end inlet, its lower opening serving as a warp end outlet and its front opening narrower than the interior of the warp feeding slit itself; and the nozzle is further provided therein with an air injection port adapted to inject a stream of pressurized air downwardly into the warp end feeding slit substantially in the form of a parallel-flow and thereby to produce an air stream flowing from the warp end inlet towards the warp end outlet under an ejector effect.
Abstract:
AN apparatus individually separates a plurality of dropper bars which are suspended from a dropper supporting rod. A nozzle first blows the dropper bars along the dropper supporting rod to a position at which the dropper bars are to be separated. A lifting device lifts the lower end of a forwardmost dropper bar which is to be separated from the remaining dropper bars, and advances the forwardmost dropper bar along the dropper supporting rod. A slicer than moves the lower end of the dropper bar, lifted and advanced by the lifting device, in the direction of the width of the dropper bar. A separating device receives the dropper bar from the slicer and attracts and holds the lower end of the dropper bar with a magnet. The separating device then separates the received dropper bar from the remaining dropper bars. A shutter mechanism operates in an interlocking relation with the separating device to release the upper ends of the dropper bars one by one.
Abstract:
A measuring device such as a spectrometer uses an automatic sample changer for carrying a plurality of samples. The automatic sample changer may include a rotary circular disk rotatable around its central shaft by a stepping motor for changing positions of the samples which are positioned in a circle around the central shaft of the disk. A memory device preliminarily storing control data for each of different kinds of automatic sample changers is provided. The automatic sample changer, when connected to a control unit in the main body, serves to receive control signals for controlling motions of the motor and to transmit data stored in the memory device through a connector. The main body of the measuring device contains a control unit which serves to read out the control data from the memory device, to use the received control data to generate the control signal and to transmit the generated control signal to the automatic sample changer.
Abstract:
A thread tensioning apparatus includes a pair of spaced arms that are simultaneously rotatable relative to supports to which the arms are mounted, a brush for catching threads and drawing out the threads from a thread beam, the brush being attached to the arms so as to be movable longitudinally of the arms and extending substantially perpendicularly to the arms, a movable member that is attached to each of the arms so as to be movable in the longitudinal direction of the arms, a comb that is attached to the movable member and extends substantially parallel to the drawing-out brush, a thread arranging brush that is rotatably attached to the movable member and extends substantially parallel to the comb, a pair of spaced clamp bars that are attached to the arms and extend substantially parallel to the drawing-out brush, and a pair of clamp members that are attached to the supports to cooperate with the clamp bars.
Abstract:
A thread separating apparatus separates an outermost thread from a large number of threads arranged substantially parallel and in close proximity to each other within one plane. The apparatus has a movable table that is movable in a direction which is parallel to the plane in which the threads are arranged and which is substantially perpendicular to the threads. A thread guide member and a thread separating device project from the movable table in the direction of movement of the movable table. The guide member has a slit in which threads are to be aligned. The thread separating device has a pair of separating members which can be opened and closed as desired to separate the outermost thread from the other threads. The movable table is further provided with a detector for detecting in a non-contact manner a diameter of thread which is to be separated, and a switch that is activated by the separated thread.
