FR2534818A1 - SELF-ADJUSTING BAND FOR OVERLAPPING THE UPPER LINK FOR FIXING TENNIS NETS - Google Patents

Abstract

THE SUBJECT OF THE INVENTION RELATES TO THE TECHNICAL SECTOR OF SELF-GRIPPING ASSEMBLY MEANS. THE BAND IS REMARKABLE IN THAT IT CONTAINS ON THE SAME SIDE OPPOSING MALE AND FEMALE TRANSVERSAL PARTS ARRANGED IN ROWS ACCORDING TO THE LENGTH OF THE BAND SO AS TO BE SELF-GRIP THROUGH THE INTERSTICES OF THE TENNIS NET AFTER LONG BENDING OF THE SAID BAND AND OVERLAP OF THE TIE OR UPPER FIXING CABLE OF THE SAID NET. THE INVENTION IS RELATED IN PARTICULAR TO TENNIS NETS.

Description

25348 1-8

  The present invention relates to a self-gripping strip

  intended to overlap the upper bond of

tennis nets.

  It is well understood that the tennis nets are suspended at the top by a link, such as a cable tensioned between two poles This link is also covered by a band

  folded textile arranged in overlapping and fixed by its borders

  sewing through the interstices of said net.

  It is understandable that in case of net repair or change

  of this particular # 6 N strip to its frequent wear, it is necessary to unravel it and then to replace and sew

  a new band This operation is impractical and time-consuming

  considering the length of the net that exceeds ten meters.

  According to the present invention, it has been desired to obviate

  conveniences, by producing a textile or non-textile strip with the edge or half-transverse portion of opposite male and female parts obtained directly during weaving, knitting or otherwise to be able to self-grip through the interstices of the net after longitudinal folding U-shaped and overlapping link

fixing said net.

  According to another characteristic and in the case of

  In the case of a textile strip, the opposing male and female gripping parts disposed along one side are obtained directly during weaving by means of a device mounted on the loom and allowing the formation of

  curls and mushrooms on the same side.

  These and other characteristics will emerge from

  Figure 8 is a cross-sectional profile view

  along line 8-8 of Figure 7.

  According to the invention and in the case of a self-adhesive textile strip

  gripper obtained by the method of weaving or knitting, said strip (1) is on one side with two opposite edges male and female, such as a row of loops (la) and

  a row of mushrooms or hooks (lb) constituting the

  These components (la and lb) can be

  interpenetration after longitudinal folding and folding

  the U-shaped web (1) as shown in FIG. 5.

  When weaving this band (1), the loops (la) and

  mushrooms (lb) are obtained simultaneously by incorporating locally

  the multi-strand chains (C) corresponding to the formation zone of the loops (1a), while the chains (Ca), are arranged along the normal chain arranged along the entire width and in the known manner of the intertwined chains (C and Ca). mono-strand, with a point

  very weak fusion, correspond to the opposite zone of

mushrooming (lb).

  We must consider that at first, the chains (C and Ca) are woven simultaneously with the normal chain by forming, in the known manner, following the passage of the son of frames

  and by means of lancets, the loops (1a) correspond to

  to the threads (C) and opposite other loops (lba) to be transformed in a second time for training

mushrooms (lb) or hooks.

  For this purpose, it is also intended according to the invention to equip the loom with a device placed transversely

  along the entire width and above the band (1).

  This adjustable mounted device on lateral supports (2 and 3) integral with the skeleton of the loom overlaps the belt (1) on the loop side (la and lba) after their formation but before

  its winding on the draw roller.

  It must be considered that this device is established with a heating wire (4) arranged perpendicular to the width of the loops (lba) to allow to eliminate by melting the loop heads while leaving by retraction, the vertical branches which constitute mushrooms (lb-) This thread

  heating element (4) acting in the transverse rows of the

  keys (lba) is fixed on one side to a pad (P) integral with the

  port (3), connected to a phase of an electrical circuit Next to its opposite end, the heating wire (4) is connected with the end lug (5 a) of a solid support (5) in the form of a bridge whose horizontal branch (5b) is shifted to be disposed well above the width of the loops (1a), so as to eliminate

  any heat radiation This support (5) is fixed on the opposite side

  placed on a pad (Pa) secured to the support (2) and connected

is lying.

  It is obvious that this device makes it possible to act effectively

  only on the heating wire '(4) for the formation of the mushrooms (1b), while the support (5) allows for its own

  mass to eliminate any heating.

  It is envisaged that the support (5) can be either directly insulating material internally with a conductive wire connecting the pad (Pa) to the heating wire (4), or again covered with a

insulating and refractory sheath.

  This device thus described is applicable in the same way to textile strips obtained by any other method such as the knitting process, and it is quite obvious that said strips (1) with rows of loops (la) and hooks (Ib) can have a background of

any suitable armor.

  In the same way, only one band (1) can have several

  rows of loops (la) and mushrooms (lb) arranged symmetrically

  or not in opposition but not necessarily on the border.

  It is obvious that within the scope of the invention, the self-gripping strips woven or knitted with instead of-mushrooms (lb) hooks made in the known manner, but

  always having in counterpart loops (la) arranged in op-

  position on another row to grip after transverse folding.

  The advantages are clear from the description.
