This invention relates to presses and more particularly
to a press for automatically attaching handles to fabric
It is conventional to place around the periphery of a
mattress handles by which the mattress may [be moved
and turned. These handles are typically applied directly
to the strip of fabric which forms the sides of the mat 15
For the handles to be applied, there is provided an
arched guideway 40 (FIG. 3) whose upper end extends
over the press so that handles may be easily loaded into
the apparatus from the front of the press and thence con
ducted by gravity to the reciprocating head 20. The
handles 42 (FIGS. 7 and 8) are provided with pre-at
tached pronged fasteners 44 which, as may ‘be seen in
FIG. 4, include a plurality of pointed prongs 46. These
prongs ?t in corresponding slots in the ends of the han
, tress. It is thus a primary object of the present inven
tion to provide apparatus for applying handles to such
dle (FIGS. 8 and 10) and, before attachment to the fab
ric strip, are held there by friction. After proceeding
material quickly and cheaply and with as little human

supervision as possible.
Further objects are to provide such apparatus which 20 er 5%} (FIGS. 7, 8 and 9) which is attached to the frame

the fabric 1'6. To prevent the possible bowing of the
handles the head 20 is provided with a spring loaded pin
adapted to engage a locking ring. The press has a re

So that the locking rings 62 may be automatically pro
vided as needed, the press includes a plurality of closing
dies 60 which are spaced around the peripheries of a
pair of disks 65 which may be rotated so as to bring
successive locking dies 60 into position under the respec
tive driving dies 22. The disks 65 are set into the bed
14 of the press so as to provide a ?rm support for the
fastener closing action. At a portion of each ‘disk re
moved from the operating position, there is provided a
ring tube 67 (FIGS. 1 and 2) which is adapted
to drop a single locking ring into each empty closing die
60 as it passes 'by the tube.
For rotating the disk 65 there is provided a second
