Abstract
Abstract Method and apparatus for the manipulation of sheet materials with reciprocating head machines. Each sheet of the material is mounted on a transport mechanism and controllably advanced relative to a reciprocating head. For each such advance, the sheet is pivoted by the transport mechanism into the path of the reciprocating head just before the engagement of the latter with a work piece. This permits precision control over the contact of the head with the material without disturbing the work piece.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
53 words
The method of manipulating a sheet of material with respect to a reciprocating head which comprises the steps of: (a) positioning the sheet on a pivotally transport mechanism; (b) pivotally moving the transport mechanism to position the sheet beneath the head; and (c) engaging the sheet between the head and a work piece.
Claim 2
Independent Claim
53 words
The method of manipulating a sheet of material with respect to a reciprocating head which comprises the steps of: (a) positioning the sheet on a pivotally transport mechanism; (b) pivotally moving the transport mechanism to position the sheet beneath the head; and (c) engaging the sheet between the head and a work piece.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein said transport mechanism has an axis of pivot which is offset from the axis of movement of the head.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein said transport mechanism is moved into position as said head begins its downward stroke.
Claim 5
Dependent Claim
21 words
The method of claim 3 wherein said transport mechanism is moved out of position as said head begins its upward stroke.
Claim 6
Dependent Claim
13 words
The method of claim 1 wherein said head is used for ultrasonic welding.
Claim 7
Dependent Claim
14 words
The method of claim 1 wherein said head is used for hot stamp processing.
Claim 8
Dependent Claim
25 words
The method of claim 2 wherein said transport mechanism causes a selected portion of said sheet to be positioned in the path of said head.
Claim 9
Dependent Claim
21 words
The method of claim 7 wherein the positioning of said sheet is controlled by a drive shaft having a clutch mechanism.
Claim 10
Dependent Claim
15 words
The method of claim 8 wherein said drive shaft includes an internal and external clutch.
