Abstract
In a method and apparatus for making disposable shoe covers from a substantially continuous supply of material, the material is moved continuously through a plurality of operating stations wherein two parallel sheets of the material are joined to form a shoe cover. The webs of material are drawn from two supply sources along a parallel path where an elastic band of material is attached to one edge of both webs and are united by glueing and stitching operations. In addition, when desired, a static strip is added as the web moves through the apparatus. After the webs of material have been joined, the apparatus cuts the length of joined webs into discrete lengths to define the individual shoe covers.
Claims21
An apparatus for continuous and automatic manufacture of shoe cover members comprising:
- supply means for supplying two continuous webs of a material,
- means for advancing each of said webs of material through said apparatus,
- means for sewing a continuous band of an elastic material along one lateral edge of at least one of said continuous webs of fabric material as said web moves though said apparatus,
- means for selectively applying an adhesive to at least one of said webs of material at discrete longitudinally spaced increments as said web moves through said apparatus,
- means for directing said webs of material into close parallel paths of movement through said apparatus,
- means for pressing said webs together as said webs move through said apparatus to adhere said webs together at said discrete longitudinally spaced increments,
- means for joining said webs together along the length of the first of the lateral edges thereof and along selected portions of the length of the second of the lateral edges thereof, and
- means for severing said joined webs of material at said longitudinally spaced adhesively joined segment to form individual fabric disposable shoe cover members.
A method for forming individual disposable shoe covers comprising:
- moving a web of fabric material from two continuous sources of supply,
- sewing a continuous band of an elastic material along a first lateral edge of each web of fabric material,
- applying an adhesive at discrete space increments to at least one of said webs of fabric material along the width of the web between the first lateral edge and a second lateral edge of the web and directing said webs into a close parallel path of movement to adhere said webs together in an adhesively joined segment at discrete spaced intervals,
- sewing said first lateral edges of said joined webs together along a discrete length thereof which is less than the length beteeen adjacent adhesively joined segments to define an opening at said first lateral edge between said webs of fabric material,
- sewing a second lateral edge of said joined webs together along the length thereof which is at least the length between adjacent adhesively joined segments,
- severing said joined webs of material within said adhesively joined segments to form individual fabric shoe cover members.
In an apparatus for manufacturing of fabric disposable shoe covers formed by joining together two continuous webs of fabric, a severing apparatus for severing the joined continuous webs into individual shoe covers comprising a rotating drum member carrying a plurality of radially reciprocating cutting members, means to rotate said drum, a fixed support means spaced outwardly from and concentric with said rotating drum through a substantial portion of the circumferential extent of said drum, means associated with said drum for contacting said webs as said webs are fed through said manufacturing apparatus and for pressing said webs against said fixed support means whereby said webs are driven by said drum about a substantially circular path of travel against said fixed support means, and means for selectively moving said cutting members radially outwardly to sever said webs through said joined webs to form the shoe covers.
An apparatus for continuous and automatic manufacture of a web adapted to be severed to form shoe cover members comprising:
- supply means for supplying two continuous webs of a material,
- means for advancing each of said webs of material through said apparatus,
- means for sewing a continuous band of an elastic material along one lateral edge of at least one of said continuous webs of fabric material as said web moves though said appartus,
- means for selectively applying an adhesive to at least one of said webs of material at discrete longitudinally spaced increments as said web moves through said apparatus,
- means for directing said webs of material into close parallel paths of movement through said apparatus,
- means for pressing said webs together as said webs move through said apparatus to adhere said webs together at said discrete longitudinally spaced increments, an
- means for joining said webs together along the length of the first of the lateral edges thereof and along selected portions of the length of the second of the lateral edges thereof to form joined webs which are adapted to be severed at said longitudinally spaced adhesively joined segments to form individual fabric disposable shoe cover members.
A method for forming a continuous web adapted to be severed to form individual disposable shoe covers comprising:
- moving a web of fabric material from two continuous sources of supply,
- sewing a continuous band of an elastic material along a first lateral edge of each web of fabric material,
- applying an adhesive at discrete space increments to at least one of said webs of fabric material along the width of the web between the first lateral edge and a second lateral edge of the web and directing said webs into a close parallel path of movement to adhere said webs together in an adhesively joined segment at discrete spaced intervals,
- sewing said first lateral edges of said joined webs together along a discrete length thereof which is less than the length between adjacent adhesively joined segments to define an opening at said first lateral edge between said webs of fabric material,
- sewing a second lateral edge of said joined webs together along the length thereof which is at least the length between adjacent adhesively joined segments to form joined webs of material which are adapted to be severed within said adhesively joined segments to form individual fabric shoe cover members.
