Definitions

  • My invention has for its object automatic clips for tentering machines, said clips including a base plate or table forming the lower jaw and a nipper plate or faller forming the upper jaw.
  • My invention has for its object to remove this drawback by producing an improved type of automatic clip through which the action of hot air is adapted to be exerted as directly on the selvages as on the remainder of the fabric.
  • the movable nipper plate of the clip may be associated with a wave-forming device provided inside the clip and constituted by a series of fins or the like elements the number of which is equal to that of the notches of the table and the position and breadth of which are such as will allow their engagement into the corresponding notches of the table whereby the selvage of the fabric is constrained to form regular waves inside said notches.
  • the Wave-forming device may be constituted by a series of fins or the like elements provided on the inner surface of the movable nipper plate or faller of the clip.
  • the wave-forming device may form a system independent of the clip, pivotally secured to a shaft parallel to the plane of the table or base member and provided with means cooperating with the elements carried by the movable nipper plate or faller and adapted to make the movements of the faller and those of the wave-forming device depend on one another when the clip is being opened and when it is being automatically closed.
  • the movable nipper plate or faller is preferably provided with notches arranged in corresponding relationship with those of the table and shaped so as to execute in a manner known per se a clamping of the selvage through a succession of points-or of short lines perpendicular to or parallel with the selvage.
  • Figs. 1 and 2 are respectively side and front views of a first form of execution of an automatic clip according to my invention, illustrated in its closed position, during the drying of the fabric.
  • Figs. 3 and 4 are corresponding views of the same clip in its open position, showing the association of the clip with means for forming" or rendering regular the waves or puckers of the selvage inside the notches of the clip table.
  • Fig. 5 illustrates the device for engaging the fabric with its wavy selvage inside the clip.
  • Figs. 6 and '7 are respectively aside and a front view of a second form of execution-of the clip
  • Figs. 8 and 9 are cross-sectional views through lines VIII+-VIII and IX-IX of Fig. 6 respectively, of the same form of execution, also drawn at areduced scale.
  • Figs. 10, 11 and 12 show respectively in side, front and horizontal cross-sectional views, a third form of execution of my improved clip. 7
  • l designatesthe body of the clip, 2 the nipper plate or faller pivotally secured to the axis 3, said faller ending with a nipping portion 4 and including an upper tailpiece 5 providing for the opening of the clip when it meets a stationary stop.
  • 6 designates the table or base member carrying the selvage of the fabric I which is to be treated. This faller grips the material by. means of the projection 4 pressed against said fabric or other sheet material.
  • 9 designate the nozzles adapted to blow hot air on to the fabric.
  • I] designates the usual roller preventing the complete closing of the clip as long as it rests on the fabric. When the chain moves apart, the fabric slides under the roller III until it allows the passage of the latter inside a groove II on the table, which allows the completion of the sinking of the faller and the gripping of the fabric.
  • the table or base member 6 includes a series of bars 6
  • the width of these slots is chosen such that the selvage of the fabric "may freely form waves or puckers therein without being however too large in order to avoid a deformation of theselvage. under the action of the tractional stresses.
  • The. faller 2 is provided with notches 22, projections 2
  • is such that they make point contacts. Bars 6
  • the drying fluid constituted in the case considered by hot air blown through the nozzles & and 9 acts directly and completely on the selvage, the nozzle 9 being provided if required with lateral openings allowing the oblique jets to be directed through the notches in the fall-er.
  • the regular laying of the edges of the fabric on the table or base member of the clip may be executed for instance (Figs. 3 and 4) by using a jet of compressed air or of steam blown by a nozzle l2: on to the table, said blowing being executed before the. complete closing of the fallet.
  • the regular introduction of the fabric into the clip may also be ensured through a set of two endless strips of yielding material shown respectively at [3 and N: (Fig. 5), the lower strip I 3 being preferably provided with notches corresponding with those of the clip; a blower l5 expands the selvage of the fabric. into wave shaped formation and: the faller 2 of the clip may close without risking any double clamping action.
  • a fabric plaiting or wave-forming device constituted by ribs or fins 23 disposed rearwardly of the faller.
  • the number of said. fins or ribs is equal to that of the slots E2 of the table. 6 said fins being adapted to engage said slots at. the moment of the closing of the,
  • taller I502 which grips the selvage of the fabric only when the latter will have moved from underneath the: fins 23.. -The latter by reason of their own weight increased by that of the faller I 02 make up for all the surplus of fabric and constrain said fabric to: assume a more or less marked sinusoidal shape. This. avoids the use of blowing means. although of course it is possible to associate both methods.
  • the wave forming device is constituted by a series of blades or fins l1 plvotally secured to a shaft l8 parallel. with the plane of the. table.
  • Two central fins include an upper projecting portion l-l'l' defining a slide H2 inside which is engaged a rod t9 connecting two lugs 24 provided on the inner surface.- of the faller 202.
  • the faller When the faller is brought into its open position, its rocking produces through the agency of the rod. l9- the rising motion of the projections H t and consequently of the wave-forming device as a whole until the latter enters the position illustrated in dotted lines in Fig. 10.
  • the fins I! rest on the fabric 1 which assumes a sinusoidal shape.
  • the faller does not close completely by reason of the slope H3 holding the rod I9.
  • the fabric disengages said fins, the latter sink downwardly into the notches of the table so that the faller 2 may completely close the clip and clamp the fabric.
  • the table 6 is preferably constituted by a ribbed or comb plate made of an inoxidisable metal and having a reduced thickness in order to assume a certain elasticity.
  • a ribbed or comb plate made of an inoxidisable metal and having a reduced thickness in order to assume a certain elasticity.
  • a tenter clip for treating fabrics comprising a plurality of bars forming a base member and in parallel spaced apart relation perpendicular to the location of the selvage of the fabricto be treated, the upper surface of said bars being substantially convex shaped, a body member, a shaft carried by said body member and disposed parallel to the selvage of the fabric, a faller rotatably mounted on said shaft and having a plurality of teeth, said teeth being in alinement with said bars and having convex shaped end surfaces for co-action with said first mentioned convex surfaces of said bars, whereby the contact between said surfaces of the teeth and bars is substantially a linear one, and means for urging the fabric into the spaces between said bars before the clip is closed.
  • a tenter clip for engaging sheet material comprising a base member, said base member including a plurality of spaced apart bars arranged substantially parallel to each other to permit unobstructed passage of drying fluid to the selvedge of the material, a body member, a faller mounted onfsaid' body member for pivotal movement and extending to grip said material against said base member in engaging position of said faller, and means for forming waves in said sheet material within the spaces betweensaid bars, said wave-forming means being connected for movement with said faller and being located between said faller and said base member.
