Abstract
Abstract A top cover is peeled from a component supply tape by passing the cover around a guide surface and in a peeling direction generally reverse to the feeding direction of the supply tape while moving the guide surface in the peeling direction in order to minimize the tension necessary to accomplish the peeling.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
113 words
In a method of feeding a substrate stepwise and peeling an attached cover tape therefrom in order to uncover components carried by said substrate for pick-up of said components, said peeling comprising passing said cover tape around a guide surface of a peeler arm and in a direction generally reverse to a direction of said substrate feeding and applying tension to said cover tape in said reverse direction, the improvement comprising the steps of: retracting said guide surface in said reverse direction during said peeling in order to minimize an amount of said tension necessary to accomplish said peeling; and maintaining contact between said tape cover and said guide surface during said retracting.
Claim 2
Dependent Claim
113 words
In a method of feeding a substrate stepwise and peeling an attached cover tape therefrom in order to uncover components carried by said substrate for pick-up of said components, said peeling comprising passing said cover tape around a guide surface of a peeler arm and in a direction generally reverse to a direction of said substrate feeding and applying tension to said cover tape in said reverse direction, the improvement comprising the steps of: retracting said guide surface in said reverse direction during said peeling in order to minimize an amount of said tension necessary to accomplish said peeling; and maintaining contact between said tape cover and said guide surface during said retracting.
Claim 3
Dependent Claim
30 words
An improvement as in claim 1, and further comprising the step of: performing said retracting of said guide surface via said tape cover and tension applied thereto during said peeling.
Claim 4
Dependent Claim
35 words
An improvement as in claim 1, and further comprising the steps of: advancing said guide surface in said feeding direction in concert with said substrate during said feeding; and performing said retracting after said advancing.
Claim 5
Dependent Claim
19 words
An improvement as in claim 3, and further comprising the step of: relieving said tension during said substrate feeding.
Claim 6
Dependent Claim
45 words
An improvement as in claim 4, and further comprising the steps of: positively driving said substrate and guide surface in said feeding direction; and performing said retracting of said guide surface by pulling thereon via said tension applying during said peeling and after said feeding.
Claim 7
Dependent Claim
22 words
An improvement as in claim 1, and further comprising the step of: spring biasing said guide surface in said substrate feeding direction.
Claim 8
Dependent Claim
23 words
An improvement as in claim 1, and further comprising the step of: providing substantially constant tension on said cover tape during said peeling.
Claim 9
Dependent Claim
25 words
An improvement as in claim 1, and further comprising the step of: covering each said component with a shutter during uncovering thereof by said peeling.
Claim 10
Dependent Claim
121 words
In an apparatus for feeding a substrate stepwise and peeling an attached cover tape therefrom in order to uncover components carried by said substrate for pick-up of said components, and having means for passing said cover tape around a guide surface of a peeler arm and redirecting said cover tape in a direction generally reverse to a direction of said substrate feeding and means for applying tension to said cover tape in said reverse direction, the improvement comprising: means for retracting said guide surface in said reverse direction during said peeling in order to minimize an amount of said tension necessary to accomplish said peeling; and means for maintaining contact between said tape cover and said guide surface during said retracting.
Claim 11
Dependent Claim
121 words
In an apparatus for feeding a substrate stepwise and peeling an attached cover tape therefrom in order to uncover components carried by said substrate for pick-up of said components, and having means for passing said cover tape around a guide surface of a peeler arm and redirecting said cover tape in a direction generally reverse to a direction of said substrate feeding and means for applying tension to said cover tape in said reverse direction, the improvement comprising: means for retracting said guide surface in said reverse direction during said peeling in order to minimize an amount of said tension necessary to accomplish said peeling; and means for maintaining contact between said tape cover and said guide surface during said retracting.
Claim 12
Dependent Claim
21 words
An improvement as in claim 9, said guide surface retracting means comprising: said means for applying tension to said tape cover.
Claim 13
Dependent Claim
37 words
An improvement as in claim 9, and further comprising: means for advancing said guide surface in said feeding direction in concert with said substrate during said feeding; and means for operating said retracting means after said advancing.
Claim 14
Dependent Claim
18 words
An improvement as in claim 11, and further comprising: means for relieving said tension during said substrate feeding.
Claim 15
Dependent Claim
46 words
An improvement as in claim 12, and further comprising: means for positively driving said substrate and guide surface in said feeding direction; and means for performing said retracting of said guide surface by pulling thereon via said tension applying during said peeling and after said feeding.
Claim 16
Dependent Claim
21 words
An improvement as in claim 9, and further comprising: means for spring biasing said guide surface in said substrate feeding direction.
Claim 17
Dependent Claim
22 words
An improvement as in claim 9, and further comprising: means for providing substantially constant tension on said cover tape during said peeling.
Claim 18
Dependent Claim
22 words
An improvement as in claim 9, and further comprising: shutter means for covering each said component during uncovering thereof by said peeling.
