Abstract
Abstract An apparatus for fitting spacer frames to panes of glass in the manufacture of insulating glass has a support wall and a frame which is movable towards and away from the support wall and the upper horizontal limb of which can be moved upwardly and downwardly for the purpose of adaptation to the height of a spacer frame, while retractible pins, clamp means and pressure pins for the spacer frame are provided on the frame of the apparatus.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
208 words
Apparatus for fitting spacer frames onto panes of glass with adhesive or sealant therebetween, in the course of manufacture of insulting glass panes, comprising a substantially upright support wall, conveyor means for conveying panes of glass into the apparatus, a frame-like mounting support disposed in front of the support-wall, means for moving the mounting support toward and away from the support wall, the mounting support having an upper horizontal limb which is displaceable upwardly and downwardly, a lower horizontal limb and a vertical limb disposed at an exit end of the apparatus, the frame-like mounting support having clamp means thereon, retractable pins (16) for contacting the spacer frames (19), said pins being disposed on said vertical limb (14, 14") and on said horizontal limbs (12, 15) of the frame-like support (8) in the area between the support wall (1) and clamp means (17, 17') also on said vertical and horizontal limbs, said clamp means (17, 17') comprising clamp abutments (22,32) fixedly mounted on the limbs (12, 14, 14", 15) of the frame-like mounting support (8) and clamp members (23,33) which are pivotable to a position over the clamp abutments (22, 32) and movable toward the latter into a position to hold a spacer frame (19) against said abutments.

Claim 3
Dependent Claim
49 words
Apparatus according to claim 1, and further clamp means (17, 17') on a further limb of the frame-like mounting support disposed at an entry end of the apparatus and which is parallel to the support wall, and means for reciprocating said further limb in the direction of conveying movement.
Claim 4
Dependent Claim
56 words
Apparatus according to claim 1, in which the half of the conveyor means (4) for the panes of glass (5), which is adjacent to the exit-end vertical limb (14") of the frame-like support mounting (8), is actuable independently of the half of the conveyor means (4) which is arranged at the entry end of the apparatus.
Claim 5
Dependent Claim
48 words
Apparatus according to claim 1, in which the frame-like support mounting (8) is divided into two halves, about a vertical plane (A) which is perpendicular to the plane of conveying movement, said two halves being movable toward and away from the support wall (1) independently of each other.
Claim 6
Dependent Claim
31 words
Apparatus according to claim 1, in which the clamp members (33) are pivotal into their operative position about axes which are parallel to the limbs of the frame-like support mounting (8).
Claim 7
Dependent Claim
29 words
Apparatus according to claim 1, in which the clamp members (33) are guided slidably in pivot mountings (36) and can be drawn into the operative position by actuating means.
Claim 8
Dependent Claim
38 words
Apparatus according to claim 1, in which the lower horizontal limb (15) of the frame-like support mounting (8) can be lowered slightly during conveying movement of a pane of glass (5) with a spacer frame (19) fitted thereto.
Claim 9
Dependent Claim
54 words
Apparatus according to claim 1, in which each clamp plate (23) is arranged eccentrically with respect to a shaft (25) which carries it and which extends perpendicular to the associated limb (12, 14, 15) of the frame-like support mounting (8) and is pivotable and retractable toward the clamp abutment (22) into its operative position.
Claim 10
Dependent Claim
57 words
Apparatus according to claim 8, in which, associated with each shaft (25) of the clamp plates (23), is a link member (26) which is displaceable on the shaft (25) in the longitudinal direction thereof and is non-rotatably coupled to the shaft (25), the free end of the link member being pivotally connected to an actuating rod (27).
Claim 11
Dependent Claim
52 words
Apparatus according to claim 9, in which the link member (26) has a bore and is fitted by means of said bore over the actuating shaft (25), the link member (26) in the region of the bore having a projection which slidably engages in a longitudinal groove in the actuating shaft (25).
Claim 12
Dependent Claim
25 words
Apparatus according to claim 1, in which the front surface of the pins (16), which faces the spacer frame (19), is of a curved configuration.
Claim 13
Dependent Claim
37 words
Apparatus according to claim 1, in which the front surface of the support pins (16), which faces the spacer frame (19), extends at an inclined angle with respect to the axis of movement of the pins (16).
Claim 14
Dependent Claim
25 words
Apparatus according to claim 1, in which the pins (16), by means of crankshafts (20), are movable with a combined pivoting and longitudinally shifting movement.
Claim 15
Dependent Claim
28 words
Apparatus according to claim 1, in which said clamp abutments (32) have abutments (32') thereon of resilient material adapted to engage limbs (33') of said clamp members (33).
