Abstract

Abstract A cap making apparatus and method where a body of a fabric piece is rotated along an axis through its central portion and in timed relation to the movement of an edge of the fabric through a sewing machine. A stretched elastic material is attached by the sewing machine to the fabric piece along a closed curve. In one embodiment, excess fabric is trimmed during rotation of the piece, and the axis is fixed, the curve thereby becoming a closed circle. Rotational movement may be transmitted to the central portion by gripping and rotating that portion.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 86 words
A method of forming a cap comprising the steps of rotating a fabric piece about a stationary axis through a central portion of the piece, simultaneously: a) trimming material from the fabric piece as it rotates to form it into a circular disc, and b) attaching a stretched elastic material from a source supply to the edge of the disc, further stretching the elastic material after a predetermined length has been attached to the rotating disc, and severing the elastic material from its source of supply.
Claim 2
Independent Claim 86 words
A method of forming a cap comprising the steps of rotating a fabric piece about a stationary axis through a central portion of the piece, simultaneously: a) trimming material from the fabric piece as it rotates to form it into a circular disc, and b) attaching a stretched elastic material from a source supply to the edge of the disc, further stretching the elastic material after a predetermined length has been attached to the rotating disc, and severing the elastic material from its source of supply.
Claim 3
Dependent Claim 29 words
The method of claim 1 further including the steps of cutting the fabric piece from a source of web material, and advancing and positioning the fabric piece for rotation.
Claim 4
Dependent Claim 121 words
Apparatus for forming a cap including a source of nonwoven continuous web fabric, cutting means for severing the web into fabric pieces, means to advance the fabric pieces, one after the other, to an attaching means, means for rotating a fabric piece about an axis through a central portion of the piece, said rotating means including means for gripping the central portion of the fabric piece, means, operative simultaneously and in timed relation to the rotating means, for attaching a stretched elastic material to the fabric piece in a predetermined closed curve around the axis of rotation, and trimming means positioned radially outward of the attaching means and operative in timed relation thereto for removing excess material from the fabric piece.
Claim 5
Dependent Claim 121 words
Apparatus for forming a cap including a source of nonwoven continuous web fabric, cutting means for severing the web into fabric pieces, means to advance the fabric pieces, one after the other, to an attaching means, means for rotating a fabric piece about an axis through a central portion of the piece, said rotating means including means for gripping the central portion of the fabric piece, means, operative simultaneously and in timed relation to the rotating means, for attaching a stretched elastic material to the fabric piece in a predetermined closed curve around the axis of rotation, and trimming means positioned radially outward of the attaching means and operative in timed relation thereto for removing excess material from the fabric piece.
Claim 6
Dependent Claim 147 words
Apparatus for forming a cap including means for rotating a fabric piece about an axis through a central portion of the piece, sad rotating means including a driven rotating member and a mating, freely rotatable member, said members having an operative relationship in which the fabric is gripped between the two members and rotated, means, operative simultaneously and in timed relation to the rotating means, for attaching a stretched elastic material to the fabric piece in a predetermined closed curve around the axis of rotation, a main table frame having a feed surface, wherein thE driven rotating member has a rotating surface which lies at an angle to the feed surface, means for folding the fabric piece substantially in half, and means for supporting the folded fabric, the folded fabric enclosing the driven rotatable member and being in contact with the rotating surface of the driven member.
Claim 7
Dependent Claim 147 words
Apparatus for forming a cap including means for rotating a fabric piece about an axis through a central portion of the piece, sad rotating means including a driven rotating member and a mating, freely rotatable member, said members having an operative relationship in which the fabric is gripped between the two members and rotated, means, operative simultaneously and in timed relation to the rotating means, for attaching a stretched elastic material to the fabric piece in a predetermined closed curve around the axis of rotation, a main table frame having a feed surface, wherein thE driven rotating member has a rotating surface which lies at an angle to the feed surface, means for folding the fabric piece substantially in half, and means for supporting the folded fabric, the folded fabric enclosing the driven rotatable member and being in contact with the rotating surface of the driven member.
Claim 8
Dependent Claim 29 words
The apparatus of claim 4 wherein the folding means includes a wire frame, the frame being pivotable from beneath the fabric piece to effect folding of the fabric piece.
Claim 9
Dependent Claim 116 words
Apparatus for forming a cap including means for rotating a fabric piece about an axis through a central portion of the piece, said rotating means including a driven rotating member and a mating, freely rotatable member, said members having an operative relationship in which the fabric is gripped between the two members and rotated, means, operative simultaneously and in timed relation to the rotating means, for attaching a stretched elastic material to the fabric piece in a predetermined closed curve around the axis of rotation, a tensioning hook, means for moving said hook to further stretch the elastic material, a knife member, and means for actuating said knife member for cutting the further stretched elastic material.
Claim 10
Dependent Claim 116 words
Apparatus for forming a cap including means for rotating a fabric piece about an axis through a central portion of the piece, said rotating means including a driven rotating member and a mating, freely rotatable member, said members having an operative relationship in which the fabric is gripped between the two members and rotated, means, operative simultaneously and in timed relation to the rotating means, for attaching a stretched elastic material to the fabric piece in a predetermined closed curve around the axis of rotation, a tensioning hook, means for moving said hook to further stretch the elastic material, a knife member, and means for actuating said knife member for cutting the further stretched elastic material.
