DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a stocking positioning device, primarily for use in the manufacture of panti-hose.
A large proportion of panti-hose is manufactured automatically. One machine which is used in the manufacture of panti-hose is a line closing machine such as the Takatori line closer which is described and illustrated in British Patent Number 1 575 189. A line closing machine has a number of arm assemblies each of which consists of upper and lower pairs of support arms. The upper pair of arms supports a first stocking whilst the lower pair of arms supports a second stocking and during operation the two stockings are cut and seamed together to form a pair of panti-hose.
One of the problems encountered with a machine of this type is loading each stocking onto the respective pair of support arms to ensure that each stocking is accurately positioned to ensure proper seaming together of the two stockings to form a pair of panti-hose.
An object of the invention is to provide an improved stocking positioning device which facilitates such accurate loading of two stockings for subsequent seaming.
Accordingly, the present invention provides a device for positioning a pair of stockings on a machine of the type having a number of arm assemblies each of which consists of upper and lower pairs of support arms, the upper pair supporting, in use, a first stocking and the lower pair supporting, in use, a second stocking, the two stockings being cut and seamed together, during operation of the machine, to form a pair of panti-hose, characterised in that the device comprises:
respective first means for engaging opposite sides of each stocking loaded onto an arm assembly of said machine, said first means being movable between a first, retracted position away from said stockings, and a second, operative position adjacent said stockings;
and means for moving said first means into engagement with said stockings to effect adjustment of the position of said stockings on said arm assembly;
and wherein the first means comprise an upper pair and a lower pair of belts each being capable of linear movement when contacting a stocking to effect said adjustment.
The present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a plan view of a known line closing machine;
FIG. 2 is a side view of the machine of FIG. 1, showing the rest position of a schematically illustrated positioning device of the invention;
FIG. 3 is an enlarged plan view showing an arm assembly of the machine of FIGS. 1 and 2 together with the positioning device of FIG. 2, in more detail;
FIG. 4 is a diagrammatic view in the direction of arrow A of FIG. 3 showing the positioning device in relation to the arm assembly of FIG. 3;
FIG. 5 is a plan view of the arrangement of FIG. 4;
FIG. 6 is a view similar to that of FIG. 4, but with the positioning device in its lowered, operative position;
FIG. 7 is a perspective view from above of the positioning device shown in FIG. 5;
FIG. 8 is a side elevation of the arm assembly of FIGS. 4 to 6, showing a stocking loaded on each pair of arms;
FIG. 9 is a plan view of the arm assembly of FIG. 8; and
FIG. 10a to 10l respectively show diagrammatically various views similar to that of FIG. 5, illustrating possible forms of engagement of the positioning device with the arm assembly for positioning of the stockings.
Referring to the drawings, FIG. 1 illustrates a line closing machine, such as the Takatori line closer, which has a plurality, being six in the arrangement illustrated, of arm assemblies 12 mounted on a turntable 12A, rotary indexing of which brings the assemblies 12 successively into a working position at a loading station A, in conventional manner. As can be seen from FIGS. 2 and 3, a positioning device 10 of the invention is located immediately above the arm assembly 12 at the loading station A and can be moved selectively between an upper rest position and a lower operative or working position. As will be described, a respective stocking 14 is lo
